Stochastic dynamics beyond the weak coupling limit: thermalization
arXiv:1110.3745 · doi:10.1103/PhysRevE.84.061124
Abstract
We discuss the structure and asymptotic long-time properties of coupled equations for the moments of a Brownian particle's momentum derived microscopically beyond the lowest approximation in the weak coupling parameter. Generalized fluctuation-dissipation relations are derived and shown to ensure convergence to thermal equilibrium at any order of perturbation theory.
