Abstract :
We study the relative entropy of physical systems (classical, thermodynamical and quantum systems) with Markovian evolution and subject to an external controlling force. We derive some basic results on the relative entropy production rate that considerably extend known ones. Applications to macromolecular cooling and to modifying the evolution towards equilibrium are sketched.
