Quasielastic neutron scattering and relaxation processes in proteins: analytical and simulation-based models

Abstract

The present article gives an overview of analytical and simulation approaches to describe the relaxation dynamics of proteins. Particularly emphasised are recent developments of theoretical models, such as fractional Brownian dynamics. The latter connects dynamical events seen on the pico- to nanosecond time scale, accessible to quasielastic neutron scattering, and functional dynamics of proteins on much longer time scales.
