    "abstract": "We deduce a class of non-Markovian completely positive master equations which\ndescribe a system in a composite bipartite environment, consisting of a\nMarkovian reservoir and additional stationary unobserved degrees of freedom\nthat modulate the dissipative coupling. The entanglement-induced memory effects\ncan persist for arbitrary long times and affect the relaxation to equilibrium,\nas well as induce corrections to the quantum-regression theorem. By considering\nthe extra degrees of freedom as a discrete manifold of energy levels, strong\nnon-exponential behavior can arise, as for example power law and stretched\nexponential decays.",
