The quantum Markovian master equation is the simplest but also the most used case of study for the dynamics of open quantum systems. An interesting issue arises when the system can be clearly decomposed into two interacting subparts, which are separately coupled to two independent environments. We show a class of interactions which leaves invariant one of the subsystems in a stationary state, i.e. only one of the reduced density matrices is sensitive to the interaction. We discuss a few models of which the best known is the optomechanical coupling model, an optical cavity coupled to a small mechanical resonator.
