On Scattering Studies

M.A. Bolorizadeh

One can claim that almost all of the studies in natural science involve some kind of scattering process.

Photon, electron, proton, ions, individual atoms or molecules, etc. interact with mater to predict the structure

of matter as examples. Higher energy accelerators are being built for the interaction of particles at higher

energies, which result in new elementary particles. Usually, cross sections are measured in a scattering study.

Different types of cross sections are measured/calculated resulting in different conclusions, such as total

cross sections and differential cross sections.


9

Different aspects of scattering studies will be discussed in this talk. Total cross sections are mostly

implemented in application such as development of different technological tools. However, triply differential

cross sections are important in the detailed structural studies of matter revealing the wave functions of

different states! The emphasis will be on the experimental side of scattering measurement and their scientific

importance.

Emergent statistical bubble localization in a Z2 lattice gauge theory

H. Yarloo, M. Mohseni-Rajaee, and A. Langari

We introduce a clean cluster spin chain coupled to fully interacting spinless fermions, forming an un-

constrained Z2 lattice gauge theory (LGT), which possesses dynamical proximity effect controlled by the

entanglement structure of the initial state. We expand the machinery of interaction-driven localization to the

realm of LGTs such that for any starting product state, the matter fields exhibit emergent statistical bubble

localization, which is driven solely by the cluster interaction, having no topologically trivial noninteracting

counterpart, and thus is of a pure dynamical many-body effect. In this vein, our proposed setting provides

possibly the minimal model dropping all the conventional assumptions regarding the existence of many-body

localization. Through projective measurement of local constituting species, we also identify the coexistence

of the disentangled nonergodic matter and thermalized gauge degrees of freedom, which stands completely

beyond the standard established phenomenology of quantum disentangled liquids. As a byproduct of self-

localization of the proximate fermions, the spin subsystem hosts the long-lived topological edge zero modes,

which are dynamically decoupled from the thermalized background Z2 charges of the bulk, and hence

remains cold at arbitrary high-energy density. This provides a convenient platform for strong protection of

the quantum bits of information, which are embedded at the edges of completely ergodic subsystem; the

phenomenon that in the absence of such proximity-induced self-localization could, at best, come about with a

prethermal manner in translational invariant systems. Finally, by breaking local Z2 symmetry of the model,

we argue that such admixture of particles no longer remains disentangled and the ergodic gauge degrees of

freedom act as a “small bath” coupled to the localized components.

Polarization tensor for tilted Dirac fermion materials: Covariance in deformed

Minkowski spacetime

Z. Jalali-Mola and S. A. Jafari

The rich structure of solid state physics provides us with Dirac materials the effective theory of which enjoys

the Lorentz symmetry. In nonsymmorphic lattices, the Lorentz symmetry can be deformed in a way that the

null energy-momentum vectors will correspond to the on-shell condition for tilted Dirac cone dispersion. In

this sense, tilted Dirac/Weyl materials can be viewed as solid state systems where the effective spacetime is

nonMinkowski. In this work, we show that the polarization tensor for tilted Dirac cone systems acquires a

covariant form only when the spacetime is considered to be an appropriate deformation of the Minkowski

spacetime that is compatible with the dispersion. As a unique consequence of the deformation of the

geometry of the spacetime felt by the electrons in tilted Dirac cone materials, the Coulomb density-density

interactions will generate corrections in both longitudinal and transverse channels. Therefore the transverse

photons also participate in mediating the Coulomb forces, implying emergent Amperean forces associated

with the tilt of the spacetime.

Detuning control of Rabi vortex oscillations in light-matter coupling

Amir Rahmani and Lorenzo Dominici

We study analytically the dynamics of vortices in strongly coupled exciton-photon fields in the presence of

energy detuning. We derive equations for the vortex core velocity and mass, where they mainly depend on

Rabi coupling and the relative distance between the vortex cores in photon and exciton fields, and as a result,

core positions oscillate in each field. We use Magnus force balanced with a Rabi-induced force to show that

the core of the vortex behaves as an inertial-like particle. Our analysis reveals that the core is lighter on the

periphery of the beam and therefore it is faster in that region. While detuning induces oscillations in

population imbalance of components through the relative phase between coupled fields, in the presence of

topological charges detuning can control the orbital dynamics of the cores. Namely, it causes the vortex core

http://https/journals.aps.org/prb/abstract/10.1103/PhysRevB.100.075113

to move in larger or smaller orbits with different velocities and changes angular momentum and energy

content of the vortex field.

Induced superconductivity in Fermi arcs

Z. Faraei and S. A. Jafari

ABSTRACT When the interface of a superconductor (SC) with a Weyl semimetal (WSM) supports Fermi

arcs, the chirality blockade eliminates the induction of superconductivity into the bulk of time-reversal

symmetry (TRS) breaking WSM. This leaves the Fermi arc states as the only low-energy degrees of freedom

in the proximity problem. Therefore the SC | WSM system will be a platform to probe transport properties

which involve only the Fermi arcs. With a boundary condition that flips the spin at the boundary, we find a Z

2 protected Bogoliubov Fermi contour (BFC) around which the Bogoliubov quasiparticles disperse linearly.

The resulting BFC and excitations around it leave a distinct T 2 temperature dependence in their contribution

to specific heat. Furthermore, the topologically protected BFC being a Majorana Fermi surface gives rise to a

zero-bias peak, the strength of which characteristically depends on the length of Fermi arc and tunneling

strength. For the other BC that flips the chirality at the interface, instead of BFCs, we have Bogoliubov-Weyl

nodes whose location depends on the tunneling strength.

Vortex bound states of charge and magnetic fluctuations induced topological

superconductors in heterostructures

Hossein Hosseinabadi, Mehdi Kargarian

The helical electron states on the surface of topological insulators or elemental bismuth become unstable

toward superconducting pairing formation when coupled to the charge or magnetic fluctuations. The latter




12

gives rise to pairing instability in chiral channels $d_{xy} \pm i d_{x^2-y^2}$ , as has been observed

recently in the epitaxial Bi/Ni bilayer system at relatively high temperature, while the former favors a pairing

with zero total angular momentum. Motivated by this observation we study the vortex bound states in these

superconducting states. We consider a minimal model describing the superconductivity in the presence of a

vortex in the superconducting order parameter. We show that zero-energy states appear in the spectrum of

the vortex core for all pairing symmetries. Our findings may facilitate the observation of Majorana modes

bounded to the vortices in heterostructures with no need for a proximity-induced superconductivity and

relatively large value of Δ/E_F.

Anderson localization of surface plasmons in monolayer graphene

Milad Sani and M. Hosseini Farzad

Graphene is a two-dimensional material that has been highly regarded with its unique features to excite

surface plasmonic waves. In this paper, we present the Anderson localization of surface plasmons in

monolayer graphene. Here we proposed an active plasmonic device that consists of a monolayer graphene on

silicon random grating to trap the surface plasmons in local cavities that are created by random multiple

scattering. The quality factor of localized graphene surface plasmons (GSPs) is greater than the

corresponding factor for uniformly distributed GSPs in periodic silicon substrate (reported before) up to

three times.The field intensity of spatially localized GSPs in monolayer graphene is increased by a factor of

15 compared to GSPs in periodic grating. Our simulation results also show that the bandwidth of excitation

spectrum of GSPs is extended as a result of introducing randomness in period in order to realize the desired

random grating structure. Although the tuning of resonance frequencies of Anderson localized GSPs is a

challenging task due to its random nature, here we tune the resonance frequencies of localized surface

plasmons by using an external gate voltage for adjusting the Fermi level of monolayer graphene.

Superconducting Phases in Lithium Decorated Graphene LiC6

Rouhollah Gholami, Rostam Moradian, Sina Moradian, Warren E. Pickett

A study of possible superconducting phases of graphene has been constructed in detail. A realistic tight

binding model, fit to ab initio calculations, accounts for the Li-decoration of graphene with broken lattice

symmetry, and includes s and d symmetry Bloch character that influences the gap symmetries that can arise.

The resulting seven hybridized Li-C orbitals that support nine possible bond pairing amplitudes. The gap

equation is solved for all possible gap symmetries. One band is weakly dispersive near the Fermi energy

along Γ → M where its Bloch wave function has linear combination of dx2−y2 and dxy character, and is

responsible for dx2−y2 and dxy pairing with lowest pairing energy in our model. These symmetries almost

preserve properties from a two band model of pristine graphene. Another part of this band, along K → Γ, is

nearly degenerate with upper s band that favors extended s wave pairing which is not found in two band

model. Upon electron doping to a critical chemical potential μ1 = 0.22 eV the pairing potential decreases,

then increases until a second critical value μ2 = 1.3 eV at which a phase transition to a distorted s-wave

occurs. The distortion of d- or s-wave phases are a consequence of decoration which is not appear in two

band pristine model. In the pristine graphene these phases convert to usual d-wave or extended s-wave

pairing.

in tilted Dirac cone systems

S. A. Jafari

We show that the continuum limit of the tilted Dirac cone in materials such as 8−Pmmn borophene and

layered organic conductor α-(BEDT-TTF)2I3 corresponds to deformation of the Minkowski space-time of

Dirac materials. From its Killing vectors we construct an emergent tilted-Lorentz (t-Lorentz) symmetry

group for such systems. As an example of the t-Lorentz transformations we obtain the exact solution of the

Landau bands for a crossed configuration of electric and magnetic fields. For any given tilt parameter 0≤δ<1,

if the ratio χ=vFBz/Ey of the crossed magnetic and electric fields satisfies χ≥1+δ, one can always find

appropriate t-boosts in both valleys labeled by η=±1 in such a way that the electric field can be t-boosted

away, whereby the resulting pure effective magnetic field Bηz governs the Landau level spectrum around

each valley η. The effective magnetic field in one of the valleys is always larger than the applied

perpendicular magnetic field. This amplification comes at the expense of of diminishing the effective field in

the opposite valley and can be detected in various quantum oscillation phenomena in tilted Dirac cone

systems. Tuning the ratio of electric and magnetic fields to χmin=1+δ leads to valley selective collapse of

Landau levels. Our geometric description of the tilt in Dirac systems reveals an important connection

between the tilt and an incipient “rotating source” when the tilt parameter can be made to depend on space-

time in a certain way.

Microscopic Sources of Solid-State NMR Shielding in Titanate of Alkaline Earth

Perovskite Metals

Javad Nematollahi and Saeid Jalali-Asadabadi

Nuclear magnetic resonance (NMR) parameters are calculated and analyzed in a series of titanate of alkaline

earth perovskites to explore microscopic sources of their magnetic shieldings using a full-potential-based

NMR scheme. In this method, there is no approximation to calculate the induced current density. The slope

of the correlation between various approaches and available experimental data is successfully reproduced

very close to the required ideal value (−1). Our NMR results are consistent with the experimental data and

the available theoretical results calculated by the gauge-including projector augmented-wave (GIPAW)

method. Moreover, we have predicted the chemical shifts of the compounds in which their experimental

values have not been measured yet. Isotropic and anisotropic chemical shift parameters as well as associated

asymmetries are analyzed. The analysis explores the relation between atomic and orbital characters of the

valence and conduction bands wave functions as well as the 17O NMR shielding. Our results show that the

NMR shielding varies by around 180 ppm through the materials under question. We, in agreement with the

results reported on alkali fluorides, show that the variation of the NMR shielding in our investigated alkaline

earth titanate perovskites is mostly related to the oxygen p-states. Furthermore, we show that the NMR

chemical shifts strongly depend on the shape of the unoccupied titanium-d density of states (DOS) and

alkaline-earth metals-d DOSs as well as their locations in the conduction region with respect to the Fermi

level. It is also shown that the shielding calculated for the ordinary ice is less by 71.2 ppm than that derived

for the water using TB-mBJ.

Abstract In this paper, the spin transfer torque (STT) and the exchange coupling of the Josephson junctions

containing the interesting cases of diffusive/ballistic-triplet/singlet ferromagnetic superconductor (FS)

materials are investigated. First, the diffusive FS1/F c /FS2 structures with F c being a junction consisting of

ferromagnetic and normal metal parts as well as insulating barriers are investigated. Secondly, the ballistic

Josephson junction containing the triplet chiral p/wave FS reservoirs is studied. Using the Nazarov quantum

circuit theory for the diffusive structures, it is found that the antiparallel/parallel or vice versa

parallel/antiparallel transition of the favorable exchange coupling takes place due to the appearance of the

only out-of-plane STT. Furthermore, the analyze of the phase difference interval in which an interlayer

length-induced antiparallel/parallel transition can be occurred, is performed. Afterward, the mentioned

ballistic structure is dealt with solving the 16 16 Bogoliubov–de-Gennes equation. It is found that although

the exchange fields of the FS are laid in the z and y direction, the STT interestingly exists in all three

directions of x, y and z. This exciting finding suggests that the favorable equilibrium configuration

concerning the least exchange coupling occurs in the relative exchange field direction different from 0 or \pi.

Controlled switching of a single CuPc molecule on Cu(111) at low temperature

S. Fremy-Koch, A. Sadeghi, R. Pawlak, S. Kawai, A. Baratoff, S. Goedecker, E. Meyer, T. Glatze

Low temperature measurements of the tunneling current as a tunction of the applied bias voltage have been

performed on a dense constant-height grid above individual copper phthalocyanine molecules adsorbed on a

Cu(111) surface. By appropriate tuning of the applied bias, the molecule can be reversibly switched between

two configurations in which pairs of opposite maxima appear rotated by 90◦ in the tunneling current map.

The underlying conformations are revealed by density functional calculations including van der Waals

interactions: a C2v symmetric ground state and two energetically equivalent states, in which the molecule is

twisted and rotated around its center by ±7◦. For tip biases above 200 mV position-dependent current

switching is observed, as in previous measurements of telegraph noise [Schaffert et al., Nat. Mater. 12, 223

(2013)]. In a small voltage interval around zero the measured current becomes bistable. Switching to a

particular state can be initiated by sweeping the voltage past well-defined positive and negative thresholds at

certain positions above the molecule or by scanning at constant current and a reduced reverse bias.

Influence of temperature and pressure on CdTe:Ag thin film

Ebrahim Hasani & Davood Raoufi

In this work, cadmium telluride (CdTe) nanoparticles-doped Ag was deposited on Ag wafer at 150°C and of

2 × 10−5 mbar. The thickness of thin films is 80 nm. The results of the XRD analysis show the formation of

CdTe cubic phase and CdTe:Ag with a strong preferential orientation (220) at 150°C. The particle size in this

orientation obtained about 13.00 nm. CdTe films were annealed at temperatures of 300 and 500°C and were

placed under pressures of 1 × 10−4 and 6.5 × 10−4 mbar to investigate the effect of annealing and vacuum

pressure changes on particle size, respectively. UV–vis measurements indicate the optical band gap for

CdTe:Ag thin films is 1.75 eV and decreases with increasing the annealing temperature and pressure.

Finally, to study the morphology of CdTe:Ag thin films, SEM analysis was done. The results revealed that

variations of annealing temperature are more effective to increase the particle size than variations of

pressure.

Dirac electron scattering from a cluster of electrostatically defined quantum

dots in graphene

Mahdiyeh Sadrara and MirFaez Miri

Guided by the multiparticle Mie theory, we address Dirac electron scattering from a cluster of

electrostatically defined circular quantum dots in graphene. Even a dimer composed of two quantum dots

exhibits rich physics: Not only the length of the dimer but also its inclination with respect to the incident

electron wave vector affect the scattering efficiency, scattering pattern, suppression of Klein tunneling, Fano

resonances, vortex pattern, and electron density. A finite cluster with no axis of mirror symmetry aligned

with the direction of incident electron exhibits an asymmetric scattering pattern. As a result of deflection of

charge carriers to one side of a finite sample, a transverse voltage may be generated. Our results suggest that

not only ordered but also disordered clusters of quantum dots can be used to engineer the transport properties

of the native graphene.

The effect of pressure and spin orbit interaction on topological phase and

phonon dispersion of LuX (X= Sb, Bi) compounds

Mitra Narimani , Shahram Yalameha , Zahra Nourbakhsh

In this paper, the topological phase of LuX (X = Sb, Bi) compounds under hydrostatic and biaxial pressures

is investigated based on first principles of density functional theory by WIEN2k package. To find out the Z2

topological invariants of centrosymmetric compounds with the time reversal symmetry, the Bloch functions

parity analysis can be used via electronic band structure calculations. So in this paper the Z2 topological

invariants of the LuX (X = Sb, Bi) compounds with the time reversal and inversion symmetries are

calculated using this approach. The results show that the d-p band inversion can be occurred in these

compounds due to spin orbit interaction and appropriate pressure. These compounds have the strong

electronic interaction due to their large d-electronic orbitals near the Fermi energy. The dynamic stability of

these compounds is verified by phonon modes analysis. The surface states topological phase of these

compounds are investigated based on the band structure calculations.

Thermoelectric properties of heavy fermion CeRhIn5 using density functional

theory combined with semiclassical Boltzmann theory

M. Yazdani-Kachoei , S. Jalali-Asadabadi

Experimental evidences show that Ce-based compounds can be good candidates for thermoelectric

applications due to their high thermoelectric efficiencies at low temperatures. However, thermoelectric

properties have been studied less than the other properties for CeRhIn5, a technologically and fundamentally

important compound. Thus, we comprehensively investigate the thermoelectric properties, including the

Seebeck coefficient, electrical conductivity, electronic part of thermal conductivity, power factor and

electronic figure of merit, by a combination of quantum mechanical density functional and semiclassical

Boltzmann theories, including relativistic spin–orbit interactions using different exchange–correlation

functionals at temperatures T ≤ 300 K for CeRhIn5 along its a and c crystalline axes. The temperature

dependences of the thermoelectric quantities are investigated. Our results reveal a better Seebeck coefficient,

electrical conductivity, power factor and thermoelectric efficiency at T ≪ 300, in agreement with various

other Ce-based compounds, when a high degree of localization is considered for the 4f-Ce electrons. The

Seebeck coefficient, power factor and thermoelectric efficiency are made more efficient near room

temperature by decreasing the degree of localization for 4f-Ce electrons. Our results also show that the

thermoelectric efficiency along the a crystalline axis is slightly better than that of the c axis. We also

investigate the effects of hydrostatic pressure on the thermoelectric properties of the compound at low and

high temperatures. The results show that the effects of imposing pressure strongly depend on the degree of

localization considered for 4f-Ce electrons.

analytically and predicted the critical values of transition parameter from planar to homeotropic anchoring.

The transition parameters are achieved from simulations for three particle’s elongations: k ¼ðL þ DÞ=D ¼

3:0, 4:2, and 6:0. The results are in agreement with the predicted values. In the range of small needle length

ks, HSC particles at the first layer near the walls are perpendicular to the walls but in the second layer, are

parallel to the walls. To describe this behaviour of HSC particles, we used a system of HSCs consists of two

types of molecules: free liquid crystal molecules and fixed perpendicular substrate molecules. We show that

the particles near the perpendicular HSCs substrates have parallel alignment. The results of HSCs with k ¼

3:0 and ks=k ¼ 0:8 are compared with the hard particle-wall potential. This long needle length interaction is

similar to the hard wall potential. Also our results are corresponded to Barmes and Cleaver results on hard

Gaussian overlap particles with k ¼ 3:0 and ks=k ¼ 0:8, qualitatively.

Measuring the baryon fraction in cluster of galaxies with Kinematic Sunyaev

Zeldovich and a Standard Candle

Shant Baghram

We propose a new method to use the kinematic Sunyaev-Zeldovich for measuring the baryon fraction in

cluster of galaxies. In this proposal we need a configuration in which a supernova Type Ia resides in a

brightest cluster galaxy of intermediate redshift clusters. We show this supernova Type Ia can be used to

measure the bulk velocity of a galaxy cluster. We assert that the redshift range of 0.4>z>0.6 is suitable for

this proposal. The main contribution to the deviation of standard candles distance modulus from

cosmological background prediction in this redshift range comes from peculiar velocity of the host galaxy

and gravitational lensing. In this work we argue that by the knowledge of the bulk flow of the galaxy cluster

and the cosmic microwave background photons temperature change due to kinematic Sunyaev-Zeldovich,

we can constrain the baryon fraction of galaxy cluster. The probability of this configuration for clusters is

obtained. We estimate in a conservative parameter estimation the large synoptic survey telescope can find

spectroscopically followed ∼4500 galaxy clusters with a bright cluster galaxy which hosts a type Ia

Supernova each year. Finally, we show the improving of the distance modulus measurement is the key

improvement in future surveys which will be crucial to detect the baryon fraction of cluster with the

proposed method.

Ginzburg-Landau Theory of Dark Energy: A Framework to Study Both

Temporal and Spatial Cosmological Tensions Simultaneously

Abdolali Banihashemi, Nima Khosravi, Amir H. Shirazi

A dark energy model (DE) is proposed based on Ginzburg-Landau theory of phase transition (GLT). This

model, GLTofDE, surprisingly provides a framework to study not only temporal tensions in cosmology e.g.

H0 tension but also spatial anomalies of CMB e.g. the hemispherical asymmetry, quadrupole-octopole

alignment and its orthogonality to dipole simultaneously. In the mean field approximation of GLTofDE, the

potential is broken spontaneously. We modeled this transition and showed that GLTofDE can resolve both

the H0 tension and Lyman-α anomaly in a non-trivial way. According to χ2-analysis the transition happens at

zt=0.746+0.028−0.039 while H0=73.5±1.1 km/s/Mpc and Ωk=−0.196+0.049−0.033 which are consistent

with the latest H(z) reconstructions. In addition, the GLTofDE proposes a framework to address the CMB

anomalies when it is considered beyond the mean field approximation. In this regime existence of a long

wavelength mode is a typical consequence which is named the Goldstone mode in the case of continuous

symmetries. This mode, which is an automatic byproduct in GLTofDE, makes different directions of the sky

see different cosmological constants. This means one side of the sky should be colder than the other side

which can describe observed dipole in CMB. In addition between initial stochastic pattern and the final state

with one long wavelength mode, we can observe smaller patches or protrusions of the biggest remaining

patch in the simulation. Our simulations show these protrusions are few in numbers and will be evolved

according to Alan-Cahn mechanism. These protrusions can give an additional effect on CMB which is the

existence of aligned quadrupole-octopole mode and its direction should be orthogonal to the dipole direction.

We conclude that GLTofDE is a very rich framework both theoretically and phenomenologically.

Numerical simulations of ultra-diffuse dwarf galaxies

Haghi, Hosein; Kroupa, Pavel; Banik, Indranil; Wu, Xufen; Zonoozi, Akram Hasani;

Javanmardi, Behnam; Ghari, Amir; Müller, Oliver; Dabringhausen, Jörg; Zhao, Hongsheng

The ultra-diffuse dwarf galaxy NGC 1052-DF2 (DF2) has 10 (11) measured globular clusters (GCs) with a

line-of-sight velocity dispersion of ζ =7.8^{+5.2}_{-2.2} km s-1 (ζ =10.6^{+3.9}_{-2.3} km s-1). Our

conventional statistical analysis of the original 10 GCs gives ζ =8.0^{+4.3}_{-3.0} km s-1. The overall

distribution of velocities agrees well with a Gaussian of this width. Due to the non-linear Poisson equation in

MOND, a dwarf galaxy has weaker self-gravity when in close proximity to a massive host. This external

field effect is investigated using a new analytic formulation and fully self-consistent live N-body models in

MOND. Our formulation agrees well with that of Famaey and McGaugh. These new simulations confirm our

analytic results and suggest that DF2 may be in a deep-freeze state unique to MOND. The correctly

calculated MOND velocity dispersion agrees with our inferred dispersion and that of van Dokkum et al. if

DF2 is within 150 kpc of NGC 1052 and both are 20 Mpc away. The GCs of DF2 are however significantly

brighter and larger than normal GCs, a problem which disappears if DF2 is significantly closer to us. A

distance of 10-13 Mpc makes DF2 a normal dwarf galaxy even more consistent with MOND and the 13 Mpc

distance reported by Trujillo et al.. We discuss the similar dwarf DF4, finding good agreement with MOND.

We also discuss possible massive galaxies near DF2 and DF4 along with their distances and peculiar

velocities, noting that NGC 1052 may lie at a distance near 10 Mpc.

22

cosmological simulations. We analyse more than 300 simulated massive clusters, from `The Three Hundred

Project, and investigate the connection between mass bias and several diagnostics extracted from synthetic

X-ray images of these simulated clusters. We find that the azimuthal scatter measured in 12 sectors of the X-

ray flux maps is a statistically significant indication of the presence of an intrinsic (i.e. 3D) clumpy gas

distribution. We verify that a robust correction to the hydrostatic mass bias can be inferred when estimates of

the gas inhomogeneity from X-ray maps (such as the azimuthal scatter or the gas ellipticity) are combined

with the asymptotic external slope of the gas density or pressure profiles, which can be respectively derived

from X-ray and millimetric (Sunyaev-Zeldovich effect) observations. We also obtain that mass

measurements based on either gas density and temperature or gas density and pressure result in similar

distributions of the mass bias. In both cases, we provide corrections that help reduce both the dispersion and

skewness of the mass bias distribution. These are effective even when irregular clusters are included leading

to interesting implications for the modelling and correction of hydrostatic mass bias in cosmological analyses

of current and future X-ray and SZ cluster surveys.

Galaxy rotation curves and preferred reference frame effects

Hossein Ghaffarnejad and Razieh Dehghani

As an alternative to dark matter models we use generalized Jordan-Brans-Dicke scalar-vector-tensor (JBD-

SVT) gravity model to study the behavior of the rotational velocities of test particles moving around

galaxies. To do so we consider an interaction potential U(ϕ,Nμ) between the Brans-Dicke scalar field ϕ and

time like dynamical four-vector field Nμ which plays as four velocity of a preferred reference frame. We

show that at in weak field limits metric solution of the galaxy under consideration reaches to a modified

Schwarzschild-de Sitter space in which mass of the vector field plays as an effective cosmological constant.

In fact the present work proposes modification on the formulation of Newtons gravitational acceleration.

This is used to explain circular velocity of galaxies without postulating dark matter. We also check our

theoretical results with empirical baryonic Tully Fisher relation which states a linear relations between the

rotational speed of galaxies and their mass. Mathematical calculation predict a good correspondence between

our theoretical results and experimental observations for a set of 12 spiral galaxies.

Gravitational Collapse in Rastall Gravity

A. H. Ziaie, H. Moradpour, S. Ghaffari

We study spherically symmetric gravitational collapse of a homogeneous perfect fluid in Rastall gravity.

Considering a linear equation of state (EoS) for the fluid profiles, we examine the conditions under which the

collapse scenario could end in a spacetime singularity. Depending on the model parameters, the singularity

could be either naked or covered by a horizon. We find that a non-vanishing Rastall parameter could affect

the formation of apparent horizon so that, naked singularities may form for those values of EoS parameter

for which a homogeneous perfect fluid collapse in general relativity (GR) terminates at the black hole

formation. Hence the visibility of the resulting singularity depends on the Rastall parameter. The solutions

we obtain respect the weak energy condition (WEC) which is crucial for physical validity of the model.

Bending of light in a universe filled with quintessential dark energy

R. Saadati and F. Shojai

As a local effect of dynamical dark energy, bending of light in the presence of a spherically symmetric and

static black hole surrounded by quintessence has been studied. Having in mind recent observational data, we

have treated the problem as a deviation from Kottler space-time. This deviation is measured by a

perturbation parameter ϵ included in the equation of state parameter of quintessence as ω q = − 1 + 1 3 ϵ .

Here, the deflection angle is calculated and then the result is compared with [H. Arakida and M. Kasai, Phys.

Rev. D 85, 023006 (2012)] in the limit ϵ → 0 where the quintessence behaves like the cosmological constant.

It is shown that unlike the cosmological constant, the effect of quintessence on the photon energy equation

can not be absorbed into the definition of impact parameter. Moreover in this paper, we generalize the

Kiselev black hole to the case that there is a modified Chaplygin gas as the dark energy component of the

universe and show that the resulted metric can be reduced to the Kiselev metric by adjusting some arbitrary

parameters.

Practical and Optimal Heat-Bath Algorithmic Cooling

Sadegh Raeisi, Mária Kieferová, Michele Mosca

Heat-bath algorithmic cooling provides algorithmic ways to improve the purity of quantum states. These

techniques are complex iterative processes that change from each iteration to the next and this poses a

significant challenge to implementing these algorithms. Here, we introduce a new technique that on a

fundamental level, shows that it is possible to do algorithmic cooling and even reach the cooling limit

without any knowledge of the state and using only a single fixed operation, and on a practical level, presents

a more feasible and robust alternative for implementing heat-bath algorithmic cooling. We also show that our

new technique converges to the asymptotic state of heat-bath algorithmic cooling and that the cooling

algorithm can be efficiently implemented; however, the saturation could require exponentially many

iterations and remains impractical. This brings heat-bath algorithmic cooling to the realm of feasibility and

makes it a viable option for realistic application in quantum technologies.

Enhancing the efficiency of quantum annealing via reinforcement: A path-

integral Monte Carlo simulation of the quantum reinforcement algorithm

A. Ramezanpour

The standard quantum annealing algorithm tries to approach the ground state of a classical system by slowly

decreasing the hopping rates of a quantum random walk in the configuration space of the problem, where the

on-site energies are provided by the classical energy function. In a quantum reinforcement algorithm, the

annealing works instead by increasing gradually the strength of the on-site energies according to the

probability of finding the walker on each site of the configuration space. Here, by using the path-integral

Monte Carlo simulations of the quantum algorithms, we show that annealing via reinforcement can

significantly enhance the success probability of the quantum walker. More precisely, we implement a local

version of the quantum reinforcement algorithm, where the system wave function is replaced by an

approximate wave function using the local expectation values of the system. We use this algorithm to find

solutions to a prototypical constraint satisfaction problem (XORSAT) close to the satisfiability to

unsatisfiability phase transition. The study is limited to small problem sizes (a few hundreds of variables),

nevertheless, the numerical results suggest that quantum reinforcement may provide a useful strategy to deal

with other computationally hard problems and larger problem sizes even as a classical optimization

algorithm.

phase transition in a noisy Kitaev toric code model

Mohammad Hossein Zarei, Afshin Montakhab

Many aspects of the well-known mapping between the partition function of a classical spin model and the

quantum entangled state have been studied in recent years. However, the consequences of the existence of a

classical (critical) phase transition on the corresponding quantum state have been mostly ignored. In this

paper, we consider this problem for an important example of the Kitaev toric code model which has been

shown to correspond to the two-dimensional (2D) Ising model though a duality transformation. We show

that the temperature on the classical side is mapped to bit-flip noise on the quantum side. It is then shown

https://journals.aps.org/pra/abstract/10.1103/PhysRevA.98.062309


26

that a transition from a coherent superposition of a given quantum state to a noncoherent mixture

corresponds exactly to paramagnetic-ferromagnetic phase transition in the Ising model. To identify such a

transition further, we define an order parameter to characterize the decoherence of such a mixture and show

that it behaves similar to the order parameter (magnetization) of the 2D Ising model, a behavior that is

interpreted as a robust coherence in the toric code model. Furthermore, we consider other properties of the

noisy toric code model exactly at the critical point. We show that there is a relative stability to noise for the

toric code state at the critical noise which is revealed by a relative reduction in susceptibility to noise.

where the two parties do not even share a single direction, but the method can be generalized to other general

a Gaussian behavior for Gs(r,t) and Fs(k,t) at all times. Surprisingly, we find that these functions deviate

from Gaussian at intermediate timescales, indicating the failure of the Gaussian approximation. Furthermore,

we quantify these deviations by the non-Gaussian parameter, and we find that the deviations increase when

Short-range migration can alter evolutionary dynamics in solid tumors

Youness Azimzade and Abbas Ali Saberi

Here, we investigate how competition in the Eden model is aected by short range dispersal and the

requirement that site updates occur only after several updates of the same site have been attempted

previously. The latter models the eect of tissue or media resistance to invasion. We found that the

existence of tissue intensifies Natural Selection and de-accelerating Genetic Drift, both to a limited extent.

More interestingly, our results show that shortrange migration can eliminate genetic demixing and conceal

natural selection.

Particle velocity controls phase transitions in contagion dynamics

Jorge p. Rodríguez, Fakhteh Ghanbarnejad, Víctor M. eguíluz

Interactions often require the proximity between particles. The movement of particles, thus, drives the

change of the neighbors which are located in their proximity, leading to a sequence of interactions. In

pathogenic contagion, infections occur through proximal interactions, but at the same time, the movement

facilitates the co-location of different strains. We analyze how the particle velocity impacts on the phase

transitions on the contagion process of both a single infection and two cooperative infections. First, we

identify an optimal velocity (close to half of the interaction range normalized by the recovery time)

associated with the largest epidemic threshold, such that decreasing the velocity below the optimal value

leads to larger outbreaks. Second, in the cooperative case, the system displays a continuous transition for low

velocities, which becomes discontinuous for velocities of the order of three times the optimal velocity.

Finally, we describe these characteristic regimes and explain the mechanisms driving the dynamics.

Quantitative phase imaging based on Fresnel diffraction from a phase plate

Samira Ebrahimi and Masoomeh Dashtdar

The structural complexity and instability of many interference phase microscopy methods are the major

obstacles toward high-precision phase measurement. In this vein, improving more efficient configurations as

well as proposing methods are the subjects of growing interest. Here, we introduce Fresnel diffraction from a

phase step to the realm of quantitative phase imaging. By employing Fresnel diffraction of a divergent (or

convergent) beam of light from a plane-parallel phase plate, we provide a viable, simple, and compact

platform for threedimensional imaging of micrometer-sized specimens. The recorded diffraction pattern of

the outgoing light from an imaging system in the vicinity of the plate edge can be served as a hologram,

which would be analyzed via the Fourier transform method to measure the sample phase information. The

period of diffraction fringes is adjustable simply by rotating the plate without the reduction of both the field

of view and fringe contrast. The high stability of the presented method is affirmatively confirmed through

comparison of the result with that of the conventional Mach–Zehnder based digital holographic method.

Quantitative phase measurements on silica microspheres, onion skins, and red blood cells ensure the validity

of the method and its ability for monitoring nanometer-scale fluctuations of living cells, particularly in real-

time.

Determination of the spectral line profile using a phase gradient step and

stationary Fourier transform spectroscopy

Ameneh Jabbari, Khosrow Hassani, and Mohammad Taghi Tavassoly

This paper introduces a new, to the best of our knowledge, simple, fast, and affordable spectroscopy

technique, in which Fresnel diffraction caused by a phase gradient step is used to determine the spectral

profile of light sources by Fourier transformation of the interferogram data. To realize the phase gradient

step, a Fresnel biprism or double mirror can be used. In principle, a single interferogram is sufficient to

obtain the line profile. To demonstrate the technique, four light-emitting diode (LED) sources have been

investigated using a Fresnel biprism with 0.52° apex angle and a Fresnel double mirror with an adjustable

angle. The obtained results are confirmed by a commercial spectrometer showing relative uncertainties on

the order of 10^−2 for the linewidth.

Use of a 4-aperture DIMM instrument for atmospheric coherence time

estimation: An analytical development

M. Panahi, R. Shomali, M. Mollabashi

We report on an analytic method to estimate the Fried parameter r 0 , average wind speed v, and

subsequently the atmospheric coherence time η 0 via a 4-aperture differential image motion monitor (DIMM)

instrument. The theory developed here shows that the velocity of defocus aberration is statistically related to

atmospheric turbulence parameters which are measured by means of angle of arrival (AA) fluctuations.

Then, using the variance of the defocus velocity of four spots and the derived analytic relation, the

atmospheric coherence time can be estimated. In parallel to the analytic work, some sequences of a star

image with 700 Hz acquisition frequency are considered to simulate the atmospheric defocus and its

variations by the 4-aperture DIMM instrument for the first 10 km near the ground in both one- and three-

layer atmospheric models. The estimations from the analytic method are found to be in good agreement with

the simulation data obtained for starlight propagating through different atmospheric conditions.

Quantum treatment of field propagation in a fiber near the zero dispersion

wavelength

A. Safaei, A. Bassi, M.A. Bolorizadeh

In this report, we present a quantum theory describing the propagation of the electromagnetic radiation in a

fiber in the presence of the third order dispersion coefficient. We obtained the quantum photon-polariton

field, hence, we provide herein a coupled set of operator forms for the corresponding nonlinear Schrödinger

equations when the third order dispersion coefficient is included. Coupled stochastic nonlinear Schrödinger

equations were obtained by applying a positive P-representation that governs the propagation and interaction

of quantum solitons in the presence of the third-order dispersion term. Finally, to reduce the fluctuations near

solitons in the first approximation, we developed coupled stochastic linear equations.

Evaluation of Robinson instability due to ILSF RF cavity Impedance

S. Massoudi, M. Amniat-talab, S. Aghaei; M. Razazian, E. Ahmadi and J. Rahighi

The present study is conducted to investigate Fokker-Planck equation in action-angle variables. The

formalism is applied for the impedance of the pillbox RF cavity with 100MHz frequency which is designed

at ILSF based on MAX-lab design. The beam instability is discussed as a function of current and storage ring

circumference. The Robinson instability occurs for dipole mode if the storage ring circumference is equal to

528m and the current is more than 410 mA. Moreover, for current of 400 mA, the storage ring circumference

values including 525 m, 527.90m and 530.97m lead to Robinson instability.

Online measurement of the optical aberrations of a thin-disk laser active

medium using the Fourier domain multiplexing method

Mohammad Reza Jafarfard, Mohammad Hossein Daemi, and Shahram Kazemi

We present an interferometric scheme for the measurement of the deformation of a thin-disk laser active

medium with visible light as the probe beam. The disk has a small wedge angle, and the coatings on both of

its sides have appreciable reflectance for visible light that prevents using a standard interferometric

profilometry procedure. The method that can acquire data in a video rate is based on the interference of three

beams, two beams reflected from both sides of the disk and one the reference beam of the interferometer. To

obtain the phase variations caused by the deformation of the disk, a Fourier domain multiplexing method has

been utilized. The optical setup was designed in such a manner that these three beams were separated in the

Fourier domain. The measured data for different deformation profiles of the disk well agree with those

obtained with profilometry with an IR probe beam. This method is a fast and simple method since only a

single shot in a CCD sensor is required to acquire the morphology of the active medium in thin-disk lasers.

Resonance fluorescence of a hybrid semiconductor-quantum-dot–metal-

Atefeh Mohammadzadeh and MirFaez Miri

We study the spectrum and statistical properties of photons scattered from a semiconductor-quantum-dot–

metal-nanoparticle system under monochromatic and bichromatic excitations. We rely on the Bloch equation

to describe the evolution of the density matrix of the quantum dot. We pay attention to the self-interaction of

the quantum dot in the presence of the nanoparticle. Going beyond the dipole approximation, we show that

the system exhibits optical responses of different character in different regions of the quantum dot dipole

moment versus the nanoparticle radius phase diagram. In the strong transition and bistability regions, upon

changing the initial state, a pronounced fluorescence spectrum may become a faint one, and an oscillatory

intensity-intensity correlation may become a monotonically increasing one. The amplitudes, frequencies, and

Light scattering through the graphene oxide liquid crystal in a micro-channel

M. Arshadi pirlar, M. Rezaei mirghaed, Y. Honarmand, S. M. S. Movahe, AND R.

Karimzadeh

In this paper, we examine the light scattering by the flow of levitated flakes in a micro-channel to

characterize the tunable functionality of the graphene oxide liquid crystal in the nematic phase. Light

interaction with the mentioned material is decomposed to the scattered and transmitted parts and they can

determine the orientation of the flakes. Our results demonstrate that, pumping the graphene oxide sample

through the micro-channel leads to increase the amplitude of scattered light. The time averaged of scattered

light intensity grows by increasing volume fraction. We also find that, the higher volume fraction, the sooner

reaching to saturated normalized scattered intensity is. To get deep insight about our experimental results, we

rely on the general theoretical properties of the light scattering cross-section incorporating the fluctuation of

director vector and dielectric tensor. Our proposal is a promising approach to carry out the mechanical-

hydrodynamical approach for controlling the orientation of a typical liquid crystal.

We find that the thickness and chemical composition of both core and shell layers influence the borders

Even weak and strong transition regions may almost disappear. The population inversion, the upper and

lower limits of intensity where bistability occurs, the absorption, and other features of the system depend on

the nanoparticle characteristics. This facilitates the use of the hybrid system as a miniaturized bistable device

or a sensor.

Manipulating Birefringence in AgCl Thin Film Loaded by Silver Nanoparticles

under Normal and Oblique Incident Angles

Shadi Safaei Jazi and Razieh Talebi

We have induced anisotropy in AgCl thin film, which is loaded by silver nanoparticles, by irradiating a

single low power laser beam at wavelength 532 nm. The induced anisotropy in Ag-AgCl thin film is due to

the formation of gratings in the direction of light polarization for both normal and oblique angles of laser

incidence. In Ag-AgCl thin film, which was irradiated by oblique laser beam, complex grating with different

line-spaces is formed. It turns out that the line-spaces of the grating depend on the incident angle. Therefore,

by changing the incident angle of the laser beam, the morphology and optical properties of anisotropic

nanostructures formed on Ag-AgCl thin film can be manipulated. Linear birefringence and linear dichroism

are measured in these nanostructures by probe beams at different wavelengths in the visible region. Our

results show that the sample which is irradiated normally has the largest linear birefringence and linear

dichroism compared to the oblique incident samples. In the normal incident sample, the maximum value of

linear birefringence is seen at wavelength 632.8 nm (n=0.35), while the largest absolute value of linear

dichroism is observed at wavelength 532 nm, which is the same wavelength as the incident laser beam.

Enhancing optomechanical force sensing via precooling and quantum noise

cancellation

Tesfay Gebremariam, Ye-Xiong Zeng, Mojtaba Mazaheri, Chong Li

We theoretically investigate optomechanical force sensing via precooling and quantum noise cancellation in

two coupled cavity optomechanical systems. We show that force sensing based on the reduction of noise can

be used to dramatically enhance the force sensing and that the precooling process can effectively improve the

quantum noise cancellation. Specifically, we examine the effect of optomechanical cooling and noise

reduction on the spectral density of the noise of the force measurement; these processes can significantly

enhance the performance of optomechanical force sensing, and setting up the system in the resolved

sideband regime can lead to an optimization of the cooling processes in a hybrid system. Such a scheme

serves as a promising platform for quantum back-action-evading measurements of the motion and a

framework for an optomechanical force sensor.

Superconductivity versus structural parameters in calcium-doped Nd1-

xCaxFeAsO0.8F0.2 superconductors

F. Shahbaz Tehrani, V. Daadmehr

We have investigated experimentally how properties of NdFeAsO0.8F0.2 superconductor affected due to the

substitution of the Ca2+/Nd3+ doping. Based on the XRD data refinement, various structural parameters

such as lattice parameters, bond angles, bond length, and etc. were studied. We have determined the upper

limit of the calcium solubility in the NdFeAsO0.8F0.2 phase and it is restricted to x0.05. Also, we have

found that the lattice parameters and the cell volume decreased by increasing the calcium content. According

to the XRD data analysis, we have argued that these reductions are due to the variations in the bond lengths

and the bond angles of (O/F)-Nd-(O/F) and As-Fe-As i.e. “α, β” upon increasing the calcium dopant. So, we

have expected that the superconducting transition temperature (TC) will be sensitive to the calcium doping

values. Experimentally, the TC of our samples was reduced from 53 K (for x = 0) to 48 K (for x = 0.01) and

27 K (for x=0.025) and disappeared for our other sample. Then we have studied the dependence of TC and

explained according to the ferrimagnetic nature of these samples in which Ni is replaced by Cu at octahedral

In this study, we investigated whether ZnO coating on Ag nanoparticles (NPs) tunes electron flux and hole

figuration at the metal−semiconductor interface under UV radiation. This effect triggers the photoactivity

and generation of reactive oxygen species from Ag@ZnO NPs, which results in enhanced cytotoxic effects

and apoptotic cell death in human breast cancer cells (MDA-MB231). In this context, upregulation of

apoptotic cascade proteins (i.e., Bax/ Bcl2 association, p53, cytochrome c, and caspase-3) along with

activation of oxidative stress proteins suggested the occurrence of apoptosis by Ag@ZnO NPs in cancer cells

through the mitochondrial pathway. Also, preincubation of breast cancer cells with Ag@ZnO NPs in dark

conditions muted NP-related toxic effects and consequent apoptotic fate, highlighting biocompatible

properties of unexcited Ag@ZnO NPs. Furthermore, the diagnostic efficacy of Ag@ZnO NPs as computed

CMM were investigated at diferent gas concentrations and various temperatures in the dark and under UV

light. The selectivity and response time of the sensor to CMM gas were improved under UV irradiation. The

optimal operating temperatures were 225 °C and 100 °C in dark and exposing UV-irradiation, respectively.

Also the response of ZnO NRs sensor under UV excitation in humid condition was higher. The sensor was

more selective to CMM than CO2. The sensor stability was considered by repeating CMM detection for 90

In this study, UV‐Vis-NIR photodetectors based on decorated ZnO nanofibers (NFs) with optimized

coverage of Au nanoparticles (NPs) fabricated via combined simple electrospinning and sputtering

techniques are introduced. The effect of different coverages of Au NPs resulted from different Au nominal

layer thicknesses on the morphology and optical properties of the ZnO fibers are investigated through

various characterization methods. It is discovered that 4 nm Au nominal thickness provides the highest UV

on/off ratio (~460), responsivity (~332 A/W), detectivity (~2.93×1011 Jones) as well as faster rise and decay

times as compared to pure ZnO nanofibers. A broad spectral response from UV to NIR with high

photoresponsivity and fast response time (> 0.5 s) in the visible and NIR regions are achieved for the sample

decorated with 8 nm Au nominal thickness. Response to visible and IR irradiations and initial fast response

to UV are originated from localized surface plasmon resonance (LSPR) absorption of the Au NPs and

effective separation and transport of photogenerated carriers, wherein slow response to UV is due to

adsorption/desorption of oxygen species.

Abstract Recently, molybdenum disulfide (MoS2) nanoflakes, as one of the most stable layered transitional

optical properties which are different from their bulk counterparts. In this work, MoS2 nanoflakes were

synthesized by one step hydrothermal method and their application was investigated as a photothermal agent

for photothermal therapy and drug delivery. The sample structure and optical properties were characterized

by x-ray diffraction, Transmission electron microscopy, Raman spectroscopy, Fourier transform infrared and

Ultraviolet-Visible spectroscopy. These characterizations confirmed that synthesized MoS2 has been

exfoliated very well. The photothermal results indicated that the temperature of MoS2 nanoflakes rise with

irradiation of 808-nm continuous wave laser with 1Wcm−2 power density. Then numerical simulation was

used to compare their thermal properties with gained results of photothermal experiment for MoS2

nanoflakes with different concentrations. Finally, the outcome indicated that there is attractive agreement

between experimental and theoretical results

FORC investigation of Co-Ni bulk ferrite consolidated by spark plasma

Bulk samples of Co1-xNixFe2O4 (x= 0.0, 0.2, 0.4, 0.6, 0.8 1.0) were shaped by a spark plasma sintering

(SPS) process. The initial ferrite nano-powders which were prepared using a co-precipitation method were

characterized by high-resolution transmission electron microscopy (HRTEM) and Mössbauer spectroscopy.

The HRTEM showed nanoparticles with almost 5 to 35 nm average size. Mössbauer spectrometer is

employed to study the magnetic properties of ferrite nano-powders at room temperature. X-ray

diffractometer (XRD), field emission scanning electron microscopy (FESEM) coupled with EDS detector for

the chemical composition analysis and vibration sample magnetometer (VSM) equipped with FORC

software were used to characterize the bulk samples. Without any structural changes to powder samples, a

single-phase spinel structure was obtained. In the FE-SEM micrograph, the porosity decrease and

consequently the density increase are clearly visible and the EDS study confirms the presence of Fe, Co, Ni

and O ions in the fabricated samples by SPS process. The magnetic parameters such as saturation

magnetization and the coercivity showed a decreasing behavior with an increase in Ni concentration from 67

emu/g and 787 Oe to 42.77 emu/g and 151 Oe, respectively. FORC analysis implies the coercivity reduction

of bulk samples comparing with powders state in cobalt-rich ferrites is due to the multi-domain formation.

The coercivity unavoidable in nickel-rich ferrites is due to the occurrence of the multi-domain state along

with the disappearance of the superparamagnetic phase.

length ξ, and the local surface slope (ρ ≈ ζ/ξ) with the wetting behavior of the films’ surfaces. The contact

angle behavior was also studied by analyzing the variation of the energy of the system with water penetrating

into the surface cavities, and the associated Laplace pressure induced by the local surface curvature. Hence,

it was demonstrated that the wetting transition from a metastable Cassie-Baxter state to a Wenzel state as

well as the penetration of a droplet into the surface crevices occur at the smaller local surface slopes for the

higher surface energy material.

Wetting Transition from Hydrophilic to Superhydrophobic over Dendrite

Copper Leaves Grown on Steel Meshes

Raziyeh Akbari, Guilhem Godeau, Mohammadreza Mohammadizadeh, Frédéric Guittard,

Thierry Darmanin

With the development of water purification technologies, the usage of superhydrophobic meshes is increased

but the fabrication of durable and cost effective superhydrophobic meshes is still challenging. Here, the

formation of hierarchical copper fractals on stainless steel meshes and their superhydrophobicity without any

physical or chemical modification were studied. In addition, the improvement of superhydrophobicity of

surfaces during storing in a glass bottle for a long time (< one year) is reported. The structures were prepared

using electrodeposition method applying cyclic voltammetry and square pulse deposition approaches on

stainless steel meshes with 50 m, 100 m and 200 m pore sizes. The prepared layers are a composition of

copper with varying amounts of cuprite (Cu2O) depending on deposition method and mesh pore size. As-

prepared cyclic voltammetry layer on 100 m mesh showed the parahydrophobicity with the contact angle of

154° but a large sliding angle. The one-year stored samples in the glass bottle showed superhydrophobicity

with the contact angles larger than 150° and sliding angles in the range of 4° – 20°. The observed

improvement of superhydrophobicity is a great success in the realm of industrial water purification, while

most other proposed samples by the others have problems related to the durability of superhydrophobicity.

Association schemes perspective of microbubble cluster in ultrasonic fields

S.Behnia, M. Yahyavi, R. Habibpourbisafar

Dynamics of a cluster of chaotic oscillators on a network are studied using coupled maps. By introducing the

association schemes, we obtain coupling strength in the adjacency matrices form, which satisfies Markov

matrices property. We remark that in general, the stability region of the cluster of oscillators at the

synchronization state is characterized by Lyapunov exponent which can be defined based on the N-coupled

map. As a detailed physical example, dynamics of microbubble cluster in an ultrasonic field are studied

using coupled maps. Microbubble cluster dynamics have an indicative highly active nonlinear phenomenon,

were not easy to be explained. In this paper, a cluster of microbubbles with a thin elastic shell based on the

modified Keller-Herring equation in an ultrasonic field is demonstrated in the framework of the globally

coupled map. On the other hand, a relation between the microbubble elements is replaced by a relation

between the vertices. Based on this method, the stability region of microbubbles pulsations at complete

synchronization state has been obtained analytically. In this way, distances between microbubbles as

coupling strength play the crucial role. In the stability region, we thus observe that the problem of study of

dynamics of N-microbubble oscillators reduce to that of a single microbubble. Therefore, the important

parameters of the isolated microbubble such as applied pressure, driving frequency and the initial radius have

effective behavior on the synchronization state.

Back contact selenization and absorber layer etching for improvement in

Schottky diode behavior of [Mo/CIGS/Al] structure

Zahra Rajabi, Mehrdad Moradi and Mostafa Zahedifar

The effect of back contact selenization and absorber layer etching on Cu(In,Ga)Se2 (CIGS) structure for

thin-film solar cell applications was investigated. Considering the dependence of the efficiency of solar cells

on the performance of the absorber layer, it is essential to find its optimum parameters. This study deals with

the influence of selenization of Mo layer and KCN chemical etching of the absorber layer on the structure.

The Schottky diode current-voltage curves of [Glass/Mo/CIGS] samples with the selenized Mo layer showed

enhanced current intensity which was confirmed by the presence of MoSe2 phase in XRD patterns. The wet

KCN etching was used to remove the copper sulfide impurities, thereby higher shunt resistance was achieved

in the etched samples. The effectiveness of etching treatment was confirmed by SEM images and EDX

analysis. Our results showed that the selenization of the Mo layer and etching of the absorber layer lead to a

decrease in the series resistance and an increase in the sheet and shunt resistances. Moreover, the rectifying

factor was enhanced about 150% with an ideality factor of 2.87.

Changes in oriented graphitic carbon properties upon exposure to atomic

hydrogen

Ali Moafi, Omid Heidari, Babak Soltannia, Dougal McCulloch and Parviz Parvin

The oriented carbon nanostructures deposited at low and high temperatures (OCLT and OCHT) containing

distinct sp2 fractions are synthesized using filtered cathodic vacuum arc (FCVA) deposition system. Then,

the effect of atomic hydrogen content on the degree of graphitization of carbon thin film is investigated over

working temperature intervals from room temperature up to 200°C using in situ Raman spectroscopy. In fact,

above 120°C, the Pt catalytic activity nonlinearly elevates according to spillover of plentiful hydrogen atoms.

As a consequence, this gives rise to sp2-sp3 transition of OCLT nanostructure leading to drastic change of

optical and electrical properties. Furthermore, we have shown that OCLT and OCHT behave reciprocally to

change over sp2/sp3 ratios.

Controlled Plasma-Thinning of Bulk MoS2 Flakes for Photodetector

Fabrication

Foad Ghasemi1, Ali Abdollahi and Shams Mohajerzadeh

The electronic properties of layered materials are directly determined based on their thicknesses. Remarkable

progress has been carried out on synthesis of wafer-scale atomically Molybdenum disulfide (MoS2) as a two

dimensional material in the past few years in order to transform them into commercial products. Although

chemical/mechanical exfoliation techniques are enable to obtain high quality monolayer of MoS2, the lack of

suitable control in the thickness, and lateral size of the flakes restricts their benefits. As a result, a

straightforward, effective, and reliable approach is widely demanded to achieve large area MoS2 flake with

control in its thickness for opto-electronics applications. In this study, thick MoS2 flakes are obtained by a

short time bath sonication in dimethylformamide (DMF) solvent and thinned with the aid of a sequential

plasma etching process using H2, O2 and SF6 plasma. A comprehensive study has been carried out on MoS2

flakes based on SEM, AFM, Raman, Tem, and XPS measurements, which ultimately leads to a two-cyclic

plasma thinning method. In this approach, H2 does as a passivation step in the first sub-cycle, and O2:SF6

plasma acts as an etching step for removing the MoS2 layers in the second sub-cycle. Finally, we show that

this technique can be enthusiastically used to fabricate MoS2 based photodetectors with a considerable

photoresponsivity of 1.39 A/W and response-time of 0.45 s under laser excitation of 532 nm.

Structural features and surface morphology of ZrO2 thin films electron beam evaporation-deposited under

various oxygen partial pressure were studied. It was indicated tetragonal phase for all samples by XRD

pattern. The highest crystallite size calculated via Scherrer equation is observed at the oxygen partial

pressure of 7 × 10−3 mbar; that was in good agreement with the high-resolution surface images obtained by

FE-SEM. The photoluminescence spectrum of t-zirconia films exhibits an intense peak at 351 nm, this

emission decrease in intensity by elevation of oxygen partial pressures. Surface roughness profile and scaling

analyses were made by surface measurements of atomic force microscopy with using the height-height

correlation function. The roughness has the maximum value at the highest oxygen partial pressure. It has

been found that with the increase of oxygen partial pressures, lateral correlation length of samples increased,

and fractal dimension changed within the range of 2.20–2.26.

Goals of this work lye in attempts to fabricate Ag2O–TeO2–V2O5 glasses (Gs) and glass-ceramics (GCs),

determination of the mean square lattice strain and dislocation density by using Williamson–Smallman

method and specially detection of their antibacterial activity against two gram-negative bacteria of

Escherichia coli and Kelbesiella pneumoniae and also two gram-positive bacteria of Staphylococcus aureus

and Bacillus cereus. The xAg2O–40TeO2–(60-x)V2O5 (0 ≤ x ≤ 50 mol%) ternary glasses, were obtained

using the melt quenching method and so, resulted glasses were annealed at their specified crystallization

temperature (Tcr) to achieve the glass-ceramics. Then, the Williamson–Smallman method was used to

determine the mean square lattice strain and dislocation density. Further structural investigations were done

by FESEM, EDX and TEM. Also, serial dilution bioassay was performed against both before-mentioned

gram positive and gram negative bacteria (as test strains) to assess their antibacterial activity. Results show

that the highest antibacterial and bactericidal potential is devoted to G and GCs sample with x = 30, as the

optimal Ag2O content. Moreover, the antibacterial activity of the Gs and GCs on Staphylococcus aureus

bacteria is higher than Bacillus cereus bacteria and in the case of gram negatives, Escherichia coli exhibit a

more inhibition and bactericidal effect at x = 30%; in brief, the studied samples are good candidates in

biological applications.

The three-body cluster energy for the isospin asymmetric nucleonic matter in

the LOCV formalism

Azar Tafrihi

The equation of state (EOS) of the isospin asymmetric nucleonic matter (IASM) is studied in the Lowest

Order Constrained Variational (LOCV) formalism, using the AV18 two-body potential with a density-

dependent three-body interaction (TBI), which was proposed by Lagaris and Pandharipande (LP) in 1981. In



47

the LOCV framework, an adjustment mechanism is introduced for finding the appropriate parameters of the

TBI. It is shown that, assuming the TBI, the corresponding LOCV symmetric nuclear (pure neutron) matter

results fairly agree with those of Fermi Hypernetted Chain (FHNC). Also, the contribution of the averaged

three-body cluster (TBC) energy is evaluated, at different proton to neutron ratios R. Employing the TBI, up

to ρ=0.5 fm−3, the TBC energy ranges from −6 to 6 MeV per particle which considerably changes the IASM

EOS, especially at low densities. Moreover, employing the TBI, the LOCV IASM state-averaged correlation

functions (effective potentials) and the nucleon–nucleon distribution functions (NNDF) are reported. It is

illustrated that, by increasing the density (ratio R), the impact of the TBI becomes much more evident.

Finally, it should be noted that, the IASM FHNC and Monte Carlo (MC) data are not available for

comparison.

Equation of state and correlation functions of hypernuclear matter within the

lowest order constrained variational method

M. Shahrbaf, H. R. Moshfegh , M. Modarres

The lowest order constrained variational method is reformulated to find the equation of state of hypernuclear

matter. For the nucleon-nucleon interaction we employed the well-known Argonne V18 (AV18) interaction.

The equation of state is calculated using two-body central potentials for Lambda-N and Lambda-Lambda

interactions that are determined in order to reproduce the experimental data on single- and double-Lambda

hypernuclei. For the odd-state part of the Lambda-Lambda interaction, which is not known due to the lack of

experimental data, a proposed repulsive and attractive potential is employed to calculate the equation of

state. It is shown that the presence of LAmbda in the hypernuclear matter produces a strong softening of the

equation of state. The results are compared with similar calculations with another variational method. The

state-dependent energy as well as central and tensor correlation functions are studied up to J =2 for each

JLSTMT channel where related to total (J), orbital (L) and spin (S) angular momentum and isospin (T) and

the third component of isospin (MT) respectively for Lambda-N and Lambda-Lambda interactions.

Furthermore, the effect of baryon density and hyperon density as well as the type of hyperon-hyperon

interaction on the two-body correlation functions are investigated.

Isotopic yield and half-life of spontaneous fission for 284Cn and 284Fl

superheavy isobars using direct calculation and semiempirical formulas

M. R. Pahlavani, M. Joharifard

Isotopic yields and half-lives of 284Cn and 284Fl superheavy nuclei are calculated using nuclear proximity

and Coulomb potentials. The energy released in fission, Q value, driving potential (V − Q), the penetrability

through barrier, fission decay constant, and relative yield for each possible pair of fission fragments are

obtained. According to the fragments mass and charge asymmetry, the most favored binary fragmentation is

occurred for the highest Q value and the lowest driving potential. For spontaneous binary fission of 284Cn

superheavy nuclei, the higher relative yields are belong to production of 128Sn and 134Te fragments and for

284Fl superheavy isotope, the maximum yield were observed for 136Xe as one of the fission fragments. The

comparison between the obtained isotopic relative yield shows the role of magic and near-magic closed-shell

fragments in having the highest isotopic yield. Fission decay constant for each possible fragmentation is

calculated and then by summation over them, the total decay constant and fission half-life for 284Cn and

284Fl superheavy nuclei are estimated. Finally, the calculated half-lives using direct method are compared

with the results of semiempirical formulas as well as experimental data. Satisfactory agreement is achieved

between the results of this approach and the experimental data than the results of semiempirical formulas.

and UV14 accompanied by TNI. Our obtained results are in good consistency with the very recent

of the 50% credible region of the PhenomPNRT and TaylorF2 waveform models. Moreover, the effect of the

Time-frequency analysis of non-stationary neutron noise in a small modular

nuclear reactor

Shima Tayefi, Ali Pazirandeh , Mohsen Kheradmand Saadi

In this work, for the first time, the time-frequency analysis technique is proposed to analyze a nonstationary

neutron noise. The work investigates on an appropriate way to solve the neutron noise equation in the time-

frequency domain in an SMR reactor. To actualize this procedure, a computer program has been developed.

This program is based on the use of three main modules. The first is a static calculation by a finite difference

method and a power iteration algorithm for providing a database of the required neutronic parameters. The

second is the neutron noise calculations in the time-frequency domain and the extraction of the noise

characteristics by using the Wigner-Ville distribution. The third is the categorization of the neutron noise

sources based on their extracted characteristics such as the source type, the source location, the number of

sources, the time of the occurrence, the instance frequency and the noise amplitude. In the first module, the

static calculations are benchmarked by the referenced values. Then, in order to validate the static noise

calculation, the obtained result is compared to the result of the noise calculation in zero frequency. The

results of adjoint and direct methods are compared with each other to confirm the validity of the dynamic

noise calculation. The obtained results show a good agreement with each other. In addition, the obtained

results of the proposed method and Fourier method are compared with each other at the initial time.

Moreover, various noise sources, including mono and multi-frequency, are solved in the time-frequency

domain to evaluate the proposed method’s capability. All results show that the proposed method has a good

capability to solve neutron noise equation. The results obtained show that the time-frequency method gives

comprehensive results in comparison with frequency methods. Finally, it is concluded that analyzing the

behavior and to recognize the non-stationary processes in the core.

Novel air-to-tissue conversion factors for fast, epithermal and thermal

photoneutrons in a Siemens ONCOR dual energy 18 MV X-ray medical linear

accelerator

Mehdi Sohrabi, Amir Hakimi

A novel “photoneutron air-to-tissue conversion factor” determination method was developed with provision

of extensive data matrix for converting photoneutron dose equivalent at a position in air to that of a similar

position in a phantom. The conversion factors were determined along the central axis as well as on surface

and at depths of a multi-layer polyethylene phantom in a 10 cm×10 cm field of an 18 MV X-ray Siemens

ONCOR medical accelerator. Polycarbonate/10B neutron dosimeters (with/without cadmium covers) were

applied. Fast-photoneutron- induced recoil tracks and thermal/epithermal-photoneutron-induced alpha tracks

from 10B (nth,α)7Li reactions in polycarbonate were processed by ECE method, counted and converted to

photoneutron dose equivalents. Fast, epithermal and thermal photoneutron air-to-tissue conversion factors

along central axis as well as at different positions from the central axis on the surface and at 12 phantom

depths were determined. Air-totissue conversion factors for fast, epithermal and thermal photoneutrons along

the central axis follow the trends of depth dose equivalent responses. The air-to-tissue conversion factor

responses determined at different depths on transverse axis are flat. Air-to-tissue conversion factors

determined at the surface of the phantom are 1.89 ± 0.24 for sum of fast, epithermal and thermal; 3.52 ± 0.25

for sum of epithermal and thermal; 1.57 ± 0.13 for fast; 4.40 ± 0.33 for epithermal; and 3.35 ± 0.18 for

thermal photoneutrons. In conclusion, novel “photoneutron air-to-tissue conversion factors” versus distance

from the central axis were determined for the first time in data profile groups at 12 depths from the phantom

surface. These factors are highly instrumental for converting a photoneutron dose equivalent value in air to

that of tissue at the same position.

Lepton flavor universality violation in semileptonic tree level weak transitions

K. Azizi, Y. Sarac, H. Sundu

The recent deviations of the experimental data on some parameters of the tree-level semileptonic $B$ and

$B_c$ mesons decays from the standard model (SM) predictions indicate considerable violations of the

lepton flavor universality, and as a result possible new physics (NP) effects. To better understand the

possible NP effects it is necessary to study deeply the physical quantities defining these decays from many

aspects. The calculations of the physical quantities require the determinations of the hadronic form factors

entering the matrix elements of the considered transitions as the main inputs. We calculate the form factors

governing the tree-level $B_c\rightarrow J/\psi l \nu$ and $B_c \rightarrow \eta_c l \nu$ transitions within

the QCD sum rules method. The obtained form factors are used in the calculations of the branching ratios

($BR$s) of the $B_c \rightarrow J/\psi l \nu$ and $B_c \rightarrow \eta_cl \nu$ transitions as well as

$R(J/\psi)$ and $R(\eta_c)$. Our result on $R(J/\psi)$ supports the present tension between the SM theory

Multi-component dark matter in a non-Abelian dark sector

Fatemeh Elahi, Sara Khatibi

In this paper, we explore a dark sector scenario with a gauged SU(2)R and a global U(1)X ×Z2, where the

continuous symmetries are spontaneously broken to a global U(1)D. We show that in various regions of the

parameter space we can have two, or three dark matter candidates, where these dark matter particles are

either a Dirac fermion, a dark gauge boson, or a complex scalar. The phenomenological implications of this

scenario are vast and interesting. We identify the parameter space that is still viable after taking into account

the constraints from various experiments. We, also, discuss how this scenario can explain the recent

observation by DAMPE in the electron-positron spectrum. Furthermore, we comment on the neutrino mass

generation through nonrenormalizable interactions between the standard model and the dark sector.

Entropy formula in Einstein-Maxwell-dilaton theory and its validity for black

strings

M.R.Setare, H.Adami

We consider the near-horizon fall-off conditions of stationary black holes in Einstein-Maxwell-Dilaton

theory and find a conserved charge conjugate to the symmetry generator that preserves these conditions.

Subsequently, we find supertranslation, superrotation, and multiple-charge modes and calculate them for two

spacial examples: a typical static dilaton black hole and a charged rotating black string. In Einstein-

Maxwell-Dilaton theory, the supertranslation double-zero-mode charge T ð0;0Þ is not equal to the product of

the black hole entropy and the Hawking temperature. This may be seen as a problem, but it is not. There is a

Uð1Þ gauge freedom, and we use gauge fixing to fix the problem. We show that the new entropy formula

well as black holes.

Holographic complexity of anisotropic black branes

Seyed Ali Hosseini Mansoori, Viktor Jahnke, Mohammad M. Qaemmaqami, Yaithd D. Olivas

We use the complexity = action (CA) conjecture to study the full-time dependence of holographic

complexity in anisotropic black branes. We find that the time behaviour of holographic complexity of

anisotropic systems shares a lot of similarities with the behaviour observed in isotropic systems. In

particular, the holographic complexity remains constant for some initial period, and then it starts to change

so that the complexity growth rate violates the Lloyds bound at initial times, and approaches this bound from

above at later times. Compared with isotropic systems at the same temperature, the anisotropy reduces the

initial period in which the complexity is constant and increases the rate of change of complexity. At late

times the difference between the isotropic and anisotropic results is proportional to the pressure difference in

the transverse and longitudinal directions.

Scattering of the double sine-Gordon kinks

Vakhid A. Gani , Aliakbar Moradi Marjaneh, Alidad Askari, Ekaterina Belendryasova,

Danial Saadatmand

We study the scattering of kink and antikink of the double sine-Gordon model. There is a critical value of the

initial velocity vcr of the colliding kinks, which separates different regimes of the collision. At vin < vcr we

observe kinks reflection, while at vin > vcr their interaction is complicated with capture and escape windows.

We obtain the dependence of vcr on the parameter of the model. This dependence possesses a series of local

maxima, which has not been reported by other authors. At some initial velocities below the critical value we

observe a new phenomenon – the escape of two oscillons in the final state. Besides that, at vin > vcr we

found the initial kinks’ velocities at which the oscillons do not escape, and the final configuration looks like

a bound state of two oscillons.

Thermodynamics of higher-order entropy corrected Schwarzschild Beltrami de

Sitter black hole

B. Pourhassan, H. Farahani, S. Upadhyay

In this paper, we consider higher-order correction of the entropy and study the thermodynamical properties

of recently proposed Schwarzschild–Beltrami–de Sitter black hole, which is indeed an exact solution of

Einstein equation with a positive cosmological constant. By using the corrected entropy and Hawking

temperature, we extract some thermodynamical quantities like Gibbs and Helmholtz free energies and heat

capacity. We also investigate the first and second laws of thermodynamics. We find that presence of higher-

order corrections, which come from thermal fluctuations, may remove some instabilities of the black hole.

Also unstable to stable phase transition is possible in presence of the first- and second-order corrections.

Orbital angular momentum transfer via spontaneously generated coherence

Zahra Amini Sabegh, Mohammad Mohammadi, Mohammad Ali Maleki, and Mohammad

Mahmoudi

We study the orbital angular momentum (OAM) transfer from a weak Laguerre–Gaussian (LG) field to a

weak plane wave in two closed-loop three-level V-type atomic systems. In the first scheme, the atomic

system has two non-degenerate upper levels where the corresponding transition is excited by a microwave

plane wave. It is analytically shown that the microwave field induces an OAM transfer from an LG field to a

generated third field. It is demonstrated that the efficiency of the OAM transfer decreases when the thermal

velocity distribution of atoms is considered. In the second scheme, we consider a three-level V-type atomic

system with two near-degenerate excited states and study the effect of the quantum interference due to the

spontaneous emission on the OAM transfer. It is found that spontaneously generated coherence (SGC)

induces the OAM transfer from the LG field to the weak planar field, and the OAM transfer does not occur

in the absence of the SGC. The suggested models offer a rather simple method for the OAM transfer that can

be used in quantum information processing and data storage.

Efficiency enhancement in a two-stream free electron laser with a helical wiggler

Nader Mahdizadeh

Efficiency enhancement in a two-stream Free Electron Laser (FEL) by a tapered wiggler prior to saturation

regime is treated. Wave-particle interaction is described by a set of nonlinear coupled differential equations

in 1D approximation. The scaled vector potential correspond to the out-put power is plotted versus scaled

axial distance. It was found, that, the output power was enhanced to a level of almost 51.79%. Bunching

parameter was plotted and compared with the case of untapered wiggler field. It is found, that, bunching

parameter increased when tapering of the wiggler is executed. Bunching of the electrons in a phase space is

shown, too.

Laplace s-space, an analytical solution for the nuclear structure function, $F^A_2 (x,Q^2 )$. Firstly, the

results for separate nuclear parton distributions for all parton types are presented which include valence

quark densities, the anti-quark and strange sea PDFs and finally the gluon distribution. Based on the Laplace

transformation, the obtained parton distribution functions and the nuclear structure function in the x-space

are compared with the results from the AT12 Phys. Rev. C 86, 064301 (2012) model. Our calculations are in

good agreement with the available DIS experimental data as well as theoretical models which contain both

small and large values of x-Bjorken variable.We compare our nuclear PDFs sets with those from other recent

collaborations, in particular with the nCTEQ15 and HKN07 sets. The comparison between our results and

those from the literature indicates a good agreement.

Ab-initio study of electronic properties of Si(C) honeycomb structures

Nosratali Vahabzadeha, , Hamid Reza Alaei

In this work, the electronic structure of the pure and concentrated graphene and Silicene has been studied by

performing first-principles pseudo potential plane-wave calculations. The concentrated structures have

obtained by the substitution of Si(C) atoms in the graphene (Silicene), respectively. Calculation are

performed from pure graphene and continue with substitution of Si atoms (with: 12.5, 25, 37.5 and 50 mole

percentage) at different positions in the unit cell of graphene. The same calculations for Silicene and

substitution of C atoms, with similar mole percentage, in unit cell of Silicene have performed. We have

modeled lattice constant, band structure and directivity, while the position and mole fractions of substituted

atoms are changed in the studied compound. Our results showed that: the Total energy, the Density of State

(DOS), the Charge Density (CD), the opening of band gap and its directivity are strongly depends both on

the position and mole fraction of substituted Si(C) atoms. As an interesting result, we found an indirect

opened band gap, as large as 2.53 eV for silicon doped graphene. Also, it is found that both the elemental

concentration and unit cell geometry could affect remarkable advantages for band splitting and band gap

opening in theses graphene like structures, which has known the ideal structures with many promising

potential applications in the electronic, optoelectronic and spintronic.
