摘要：

We study ergodic properties of Pauli-Fierz systems - W*-dynamical systems often used to describe the interaction of a small quantum system with a bosonic free field at temperature T greater than or equal to 0. We prove that, for a small coupling constant uniform as the positive temperature T down arrow 0, a large class of Pauli-Fierz systems has the property of return to equilibrium. Most of our arguments are general and deal with mathematical theory of Pauli-Fierz systems for an arbitrary density of bosonic field.
