    "abstract": "We study the non-Markovian dynamics of a two-mode bosonic system interacting\nwith two uncorrelated thermal bosonic reservoirs. We present the solution to\nthe exact microscopic Master equation in terms of the quantum characteristic\nfunction and study in details the dynamics of entanglement for bipartite\nGaussian states. In particular, we analyze the effects of short-time\nsystem-reservoir correlations on the separability thresholds and show that the\nrelevant parameter is the reservoir spectral density. If the frequencies of the\ninvolved modes are within the reservoir spectral density entanglement persists\nfor a longer time than in a Markovian channel. On the other hand, when the\nreservoir spectrum is out of resonance short-time correlations lead to a faster\ndecoherence and to the appearance of entanglement oscillations.",
