Deviation from Equilibrium of QMS of Weak Coupling Limit Type with Respect to Uniform and Completely Nonequilibrium Invariant States

Abstract

We study the deviation from equilibrium with respect to a special class of states, the so called uniform and completely nonequilibrium, which were introduced and characterized in [11]. We compute explicitly such a deviation, we obtain an equivalent expression in terms of circulant matrices and give a bound for it. Finally, as an example, we make explicit computations in the three level case.
