Stationary State Fluctuation Theorems for Driven Langevin Systems
Abstract
Recent results on the stationary state Fluctuation Theorems for work and heat fluctuations of Langevin systems are presented. The relevance of finite time corrections in understanding experimental and simulation results is explained in the context of an exactly solvable model, namely a Brownian particle in a harmonic potential, which is dragged through the surrounding fluid. In this model, work fluctuations obey the conventional form of the fluctuation theorem while heat fluctuations satisfy an extended form. The connection with other work in recent literature is pointed out, and further generalizations are suggested.
