Abstract. An appropriate generator matrix induces in a natural way a Markov semigroup which can be applied to the construction of a continuous time Markov process whose asymptotic distribution is independent of the initial state. We propose a generator associated with a prescribed (arbitrary) distribution which turns out to be reversible for the corresponding Markov process. As an application, we show that the Markov process offers a physically plausible description of a quantum system exposed to a heat bath. The system approaches its Gibbs state corresponding to the temperature of the heat bath if its initial state commutes with the Hamiltonian.
