Quantum entanglement in the multiverse

S Robles-Pérez, PF Gonzalez-Diaz - Journal of Experimental and …, 2014 - Springer
We show that the quantum state of a multiverse made up of classically disconnected regions
of the space-time, whose dynamical evolution is dominated by a homogeneous and …

Interacting universes and the cosmological constant

A Alonso-Serrano, C Bastos, O Bertolami… - Physics Letters B, 2013 - Elsevier
In this Letter it is studied the effects that an interaction scheme among universes can have in
the values of their cosmological constants. In the case of two interacting universes, the value …

Third quantization and quantum universes

SP Kim - Nuclear Physics B-Proceedings Supplements, 2014 - Elsevier
We study the third quantization of the Friedmann-Robertson-Walker cosmology with N-
minimal massless fields. The third quantized Hamiltonian for the Wheeler-DeWitt equation in …

Conceptual Challenges on the Road to the Multiverse

A Alonso-Serrano, G Jannes - Universe, 2019 - mdpi.com
The current debate about a possible change of paradigm from a single universe to a
multiverse scenario could have deep implications on our view of cosmology and of science …

Correlations across horizons in quantum cosmology

A Alonso-Serrano, LJ Garay, GA Mena Marugán - Physical Review D, 2014 - APS
Different spacetime regions separated by horizons are not related to each other. We know
that this statement holds for classical spacetimes. In this paper we carry out a canonical …

Entanglement in a multiverse with no common space-time

SJ Robles-Pérez - arXiv preprint arXiv:1212.4598, 2012 - arxiv.org
Inter-universal entanglement may even exist in a multiverse in which there is no common
space-time among the universes. In particular, the entanglement between the expanding …
