Macroscopic Manifestation of Microscopic Entropy Production: Space-Dependent Intermittence

Statistical Mechanics 2007-05-23 v1

Abstract

We study a spatial diffusion process generated by velocity fluctuations of intermittent nature. We note that intermittence reduces the entropy production rate while enhancing the diffusion strength. We study a case of space-dependent intermittence and prove it to result in a deviation from uniform distribution. This macroscopic effect can be used to measure the relative value of the trajectory entropy.
