Inter-universal quantum entanglement
S. J. Robles-Pérez, P. F. González-Díaz
The boundary conditions to be imposed on the quantum state of the whole multiverse could be such that the universes would be created in entangled pairs. Then, inter-universal entan…
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…
Isotropic extensions of the vacuum solutions in general relativity
C. Molina, Prado Martín-Moruno, Pedro F. González-Díaz
In this work, we obtain isotropic extensions of the usual spherically symmetric vacuum geometries in general relativity. Exact and perturbative solutions are derived. The classes o…
Observing other universe through ringholes and Klein-bottle holes
Pedro F. González-Díaz, Ana Alonso-Serrano
It is argued that whereas the Shatskiy single rings produced by the gravitational inner field of a spherically symmetric wormhole and the concentric double Einstein rings generated…
Is there a Bigger Fix in the Multiverse?
Pedro F. González-Díaz
The dynamics of baby universes which are branched off in pairs from a large universe and whose respective members are entangled to each other has been studied in quantum gravity an…
Coherent states in the quantum multiverse
S. Robles-Perez, Y. Hassouni, P. F. Gonzalez-Diaz
In this paper, we study the role of coherent states in the realm of quantum cosmology, both in a second-quantized single universe and in a third-quantized quantum multiverse. In pa…
