Modified Jarzynski Relation for non-Markovian noise

Statistical Mechanics 2008-07-24 v1 Other Condensed Matter

Abstract

We demonstrate the conventional Jarzynski relation (JR) is violated for a non-Markovian process with colored noise. As an example an exactly soluble model is considered with a simple protocol for the external work performed on the system along a non-equilibrium trajectory. For that model we derive an exact expression for the dissipative energy in terms of an arbitrary correlator of the noise characterized by an autocorrelation time tct_c. As the result we find corrections to the JR in terms of tct_c. In the limiting case of a Gaussian process as well as an infinitely slow process the conventional JR is retained. The result is valid for an arbitrary colored noise.
