Stochastic thermodynamics in Sekimoto's formulation is based on a division of the world into three parts: the System, the External System, which can influence the System by modifying the System's potential energy, and the Bath. Usually the system-bath coupling is taken constant, but one could also imagine that this depends explicity on time. Does such a change lead to heat or change in internal energy (or both)? I will discuss such issues and the motivation which led me to it, problems in an approach to quantum heat.
