Nonequilibrium Dynamics, Thermalization and Entropy Production
Abstract
This paper addresses fundamental aspects of statistical mechanics such as the motivation of a classical state space with spontaneous transitions, the meaning of nonequilibrium in the context of thermalization, and the justification of these concepts from the quantummechanical point of view. After an introductory part we focus on the problem of entropy production in nonequilibrium systems. In particular, the generally accepted formula for entropy production in the environment is analyzed from a critical perspective. It is shown that this formula is only valid in the limit of separated time scales of the system's and the environmental degrees of freedom. Finally, we present an alternative simple proof of the fluctuation theorem.
