Multi-partite analysis of average-subsystem entropies
Ana Alonso-Serrano, Matt Visser
So-called average subsystem entropies are defined by first taking partial traces over some pure state to define density matrices, then calculating the subsystem entropies, and fina…
Vacuum decay in an interacting multiverse
S. Robles-Pérez, A. Alonso-Serrano, C. Bastos +1
We examine a new multiverse scenario in which the component universes interact. We focus our attention to the process of "true" vacuum nucleation in the false vacuum within one sin…
Interacting universes and the cosmological constant
A. Alonso-Serrano, C. Bastos, O. Bertolami +1
We study some collective phenomena that may happen in a multiverse scenario. First, it is posed an interaction scheme between universes whose evolution is dominated by a cosmologic…
Decoherence in an accelerated universe
S. Robles-Perez, A. Alonso-Serrano, P. F. Gonzalez-Diaz
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 thi…
