Markovian master equations
Abstract
We give a rigorous proof that under certain technical conditions the memory effects in a quantummechanical master equation become negligible in the weak coupling limit. This is sufficient to show that a number of open systems obey an exponential decay law in the weak coupling limit for a rescaled time variable. The theory is applied to a fairly general finite dimensional system weakly coupled to an infinite free heat bath.
