Fluctuation Theorems for Systems under Fokker-Planck dynamics

Abstract

We study Brownian motion driven with both conservative and nonconservative external forces. By using the thermodynamic approach of the theory of Brownian motion we obtain the Fokker-Planck equation and derive expressions for the Fluctuation Theorem in local equilibrium and in quasi-equilibrium. In local equilibrium the expressions we obtain coincide with previous results.
