Abstract. We describe some results concerning non-relativistic quantum systems
at positive temperature and density confined to macroscopically large
(infinite) regions of physical space.
In a general discussion of time-dependent thermodynamic processes,
we propose a definition of (time-dependent) entropy which has natural
physical properties. In this general framework, we show that for a class
of time-dependent perturbations approaching a limiting perturbation, the
system exhibits return to equilibrium. If the perturbation is periodic
then the system approaches a time-periodic state for large times.
We apply these results to a reservoir of non-relativistic
