Fluctuation theorems for systems under Fokker-Planck dynamics.
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 quasiequilibrium. In local equilibrium the expressions we obtain coincide with previous results.
