Entanglement entropy at critical points of classical evolution in oscillatory and exotic singularity multiverse models
Adam Balcerzak, Samuel Barroso-Bellido, Mariusz P. Dabrowski +1
Using the 3rd quantization formalism we study the quantum entanglement of universes created in pairs within the framework of standard homogeneous and isotropic cosmology. In partic…
Quantum creation of a universe-antiuniverse pair
S. J. Robles-Perez
If one analyses the quantum creation of the universe, it turns out that the most natural way in which the universes can be created is in pairs of universes whose time flow is rever…
Time reversal symmetry in cosmology and the creation of a universe-antiuniverse pair
Salvador J. Robles-Perez
The classical evolution of the universe can be seen as a parametrised worldline of the minisuperspace, with the time variable the parameter that parametrises the worldline. The…
Pre-inflation from the multiverse: Can it solve the quadrupole problem in the cosmic microwave background?
João Morais, Mariam Bouhmadi-López, Manuel Kraemer +1
We analyze a quantized toy model of a universe undergoing eternal inflation using a quantum-field-theoretical formulation of the Wheeler-DeWitt equation. This so-called third quant…
What if? - Exploring the Multiverse through Euclidean wormholes
Mariam Bouhmadi-López, Manuel Kraemer, João Morais +1
We present Euclidean wormhole solutions describing possible bridges within the multiverse. The study is carried out in the framework of the third quantization. The matter content i…
Restoration of matter-antimatter symmetry in the multiverse
Salvador J. Robles-Perez
In the multiverse, the universes can be created in entangled pairs with spacetimes that are both expanding in terms of the time variables experienced by internal observers in their…
Quantum cosmology of a conformal multiverse
Salvador J. Robles-Perez
In this paper it is studied the cosmology of a homogeneous and isotropic spacetime endorsed with a conformally coupled massless scalar field. We find six different solutions of the…
Invariant vacuum
Salvador Robles-Perez
We apply the Lewis-Riesenfeld invariant method for the harmonic oscillator with time dependent mass and frequency to the modes of a charged scalar field that propagates in a curved…
Observational consequences of an interacting multiverse
Salvador J. Robles-Perez
The observability of the multiverse is at the very root of its physical significance as a scientific proposal. In this conference we present, within the third quantization formalis…
Inter-universal entanglement in a cyclic multiverse
Salvador Robles-Perez, Adam Balcerzak, Mariusz P. Dabrowski +1
We study scenarios of parallel cyclic multiverses which allow for a different evolution of the physical constants, while having the same geometry. These universes are classically d…
Entanglement arrow of time in the multiverse
Salvador Robles-Perez
In this paper it is presented the model of a multiverse made up of entangled pairs of universes. The arrow of time obtained from the principles of thermodynamics and the arrow of t…
Quantum entanglement in the multiverse
Salvador Robles-Perez, Pedro F. Gonzalez-Diaz
In this paper it is shown that the quantum state of a multiverse made up of classically disconnected regions of the space-time, whose dynamical evolution is dominated by a homogene…
Quantum state of the multiverse
Salvador Robles-Perez, Pedro F. Gonzalez-Diaz
A third quantization formalism is applied to a simplified multiverse scenario. A well defined quantum state of the multiverse is obtained which agrees with standard boundary condit…
Dark Energy Accretion onto black holes in a cosmic scenario
Prado Martín-Moruno, Az-Eddine L. Marrakchi, Salvador Robles-Pérez +1
In this paper we study the accretion of dark energy onto a black hole in the cases that dark energy is equipped with a positive cosmological constant and when the space-time is des…
Coherent states in quantum cosmology
S. Robles-Perez, Y. Hassouni, P. F. Gonzalez-Diaz
In the realm of a quantum cosmological model for dark energy in which we have been able to construct a well-defined Hilbert space, a consistent coherent state representation has be…
Quantum theory of an accelerating universe
P. F. Gonzalez-Diaz, S. Robles-Perez
We review some of the well-known features of quantum cosmology, such as the factor ordering problem, the wave function and the density matrix, for a dark energy dominated universe,…
A dark energy multiverse
Salvador Robles-Perez, Prado Martin-Moruno, Alberto Rozas-Fernandez +1
We present cosmic solutions corresponding to universes filled with dark and phantom energy, all having a negative cosmological constant. All such solutions contain infinite singula…
