摘要：
In this paper we study the decoherence of the semiclassical branches of an accelerated universe. We use a third quantization formalism to analyze the decoherence between two branches of a parent universe caused by their interaction with the vacuum fluctuations of the space-time and with other parent universes in a multiverse scenario.
