Refined Second Law of Thermodynamics for fast random processes

arXiv:1201.3207 · doi:10.1007/s10955-012-0478-x

Abstract

We establish a refined version of the Second Law of Thermodynamics for Langevin stochastic processes describing mesoscopic systems driven by conservative or non-conservative forces and interacting with thermal noise. The refinement is based on the Monge-Kantorovich optimal mass transport. General discussion is illustrated by numerical analysis of a model for micron-size particle manipulated by optical tweezers.
