A nonequilibrium equality for free energy differences

arXiv:cond-mat/9610209 · doi:10.1103/PhysRevLett.78.2690

Abstract

An expression is derived for the classical free energy difference between two configurations of a system, in terms of an ensemble of finite-time measurements of the work performed in parametrically switching from one configuration to the other. Two well-known equilibrium identities emerge as limiting cases of this result.
