Query: On the quasi-static evolution of nonequilibrium steady states   The quasi-static evolution of steady states far from equilibrium is
investigated from the point of view of quantum statistical mechanics. As a
concrete example of a thermodynamic system, a two-level quantum dot coupled to
several reservoirs of free fermions at different temperatures is considered. A
novel adiabatic theorem for unbounded and nonnormal generators of evolution is
proven and applied to study the quasi-static evolution of nonequilibrium steady
states (NESS) of the coupled system.
