Fluctuation-dissipation relation
WebFluctuation–dissipation relations or “theorems” (FDTs) are fundamental for statistical physics and can be rigorously derived for equilibrium systems. Their applicability to non … WebThe fluctuation-response relation for Langevin dynamics in the small noise limit, recently introduced, is generalized for the purpose of computing the fluctuation spectrum of a nonequilibrium system. The fluctuation-response relation provides an efficient and operational means to compute the fluctuations around a nonequilibrium steady state. …
