Description
The Fluctuation Relation derived by Evans, Cohen and Morriss in 1993 has eventually led to a general theory of response that is exact, and not limited to small perturbations. This theory arising in the field of deterministic dynamics, nonequilibrium molecular dynamics in particular, has been recently extended to stochastic perturbations. We investigate some pedagogical example, that includes systems in extreme conditions as well as systems undergoing phase transitions, highlighting the difference between linear response and exact response.
