Abstract

Abstract: We consider an exactly soluble dynamical system with inelastic repeated harmonic perturbation. Hamiltonian dynamics is quasi-free, and it leads in the large-time limit to relaxation of initial states and to entropy production. To study correlations we consider the time evolution of subsystems. We prove a universality of dynamics driven by repeated harmonic perturbation in a short-time interaction limit.
