Energy Transport across Interfaces

in Biomolecular Systems

　Energy transport during chemical reactions or following photoexcitation in systems of

biological molecules is mediated by numerous interfaces that separate chemical groups and

molecules. Describing and predicting energy transport has been complicated by the

inhomogeneous environment through which it occurs, and general rules are still lacking.

I will discuss recent work on identification of networks for vibrational energy transport in

biomolecules and their environment, with focus on the nature of energy transfer across

interfaces. Energy transport is influenced both by structure of the biomolecular system

as well as equilibrium fluctuations of non-bonded contacts between chemical groups,

biomolecules and water along the network. While discussing our computational work on

vibrational energy transport in proteins and protein complexes I will also make contact with

a number of recent experimental studies.
