Event details

A guiding principle of equilibrium statistical mechanics is provided by the fluctuation-dissipation theorem, the simplest form of which is the Einstein relation. This relation, between steady state fluctuation properties of a system and its linear response to an external perturbation, is well understood in equilibrium but it is not known in general how to obtain such a relation for systems driven away from equilibrium. I will discuss the Einstein relation in the context of stochastic models, and illustrate how one can obtain an Einstein relation for certain nonequilibrium steady states.

About Condensed Matter lunchtime seminars

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
