Decoherence in an accelerated universe
arXiv:1111.3178 · doi:10.1103/PhysRevD.85.063511
Abstract
In this paper we study the decoherence processes of the semiclassical branches of an accelerated universe due to their interaction with a scalar field with given mass. We use a third quantization formalism to analyze the decoherence between two branches of a parent universe caused by their interaction with the vaccum fluctuations of the space-time, and with other parent unverses in a multiverse scenario.
