Abstract:

We consider a quantum spin system consisting of a finite subsystem connected to infinite reservoirs at different temperatures. In this setup we define nonequilibrium steady states and prove that the rate of entropy production in such states is nonnegative. Then we discuss the definition of entropy production, and see that there are physical questions which remain to be clarified.
