Adiabatic Otto-like quantum thermodynamical cycle in the non-quasi-static regime
Salvador J. Robles-Pérez, Salvador Castillo-Rivera
We show a finite-time Otto-like quantum thermodynamic cycle that preserves the adiabatic population structure of a time-dependent harmonic oscillator in the non-quasi-static regime…
An approach to study the adiabaticity and irreversibility in the TDHO
Salvador J. Robles-Perez, Salvador Castillo-Rivera
This work studies the relationship between parametric amplification (or particle creation), adiabaticity and irreversibility in the non-quasi-static regime of a time-dependent quan…
Hartle-Hawking's vacuum is full of Vilenkin's universe-antiuniverse pairs
Salvador J. Robles-Pérez
Within the third quantisation formalism, we find solutions of the Wheeler-DeWitt in terms of two sets of modes that can be identified with the Hartle-Hawking's no boundary conditio…
Quantum cosmology with third quantisation
Salvador J. Robles-Pérez
We review the canonical quantisation of the geometry of the spacetime in the cases of a simply and a non-simply connected manifold. In the former, we analyse the information contai…
Quantum-gravity effects for excited states of inflationary perturbations
David Brizuela, Claus Kiefer, Manuel Kraemer +1
We generalize former findings regarding quantum-gravitational corrections arising from a canonical quantization of a perturbed FLRW universe during inflation by considering an init…
Classical geodesics from the canonical quantisation of spacetime coordinates
Iñaki Garay, Salvador Robles-Pérez
A canonical quantisation of the coordinates of the spacetime within the general relativity theory is proposed. This quantisation will depend on the observer but it provides an inte…
Quantum cosmology in the light of quantum mechanics
Salvador J. Robles-Pérez
There is a formal analogy between the evolution of the universe, when this is seen as a trajectory in the minisuperspace, and the worldline followed by a test particle in a curved…
The interacting multiverse and its effect on the cosmic microwave background
Mariam Bouhmadi-López, Manuel Kraemer, João Morais +1
We study a toy model of a multiverse consisting of canonically quantized universes that interact with each other on a quantum level based on a field-theoretical formulation of the…
Effects of inter-universal entanglement on the state of the early universe
Salvador Robles-Pérez
The creation of universes in entangled pairs with opposite values of the momenta conjugated to the configuration variables of the minisuperspace would be favoured in quantum cosmol…
Cosmological perturbations in the entangled inflationary universe
Salvador J. Robles-Pérez
In this paper it is presented the model of a multiverse made up of universes which are created in entangled pairs that conserve the total momentum conjugated to the scale factor. F…
Creation of entangled universes avoids the big bang singularity
Salvador J. Robles-Pérez
The creation of universes in entangled pairs may avoid the initial singularity and it would have observable consequences in a large macroscopic universe like ours, at least in prin…
Effects of a scalar field on the thermodynamics of interuniversal entanglement
Iñaki Garay, Salvador Robles-Pérez
We consider a multiverse scenario made up of classically disconnected regions of the space-time that are, nevertheless, in a quantum entangled state. The addition of a scalar field…
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…
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…
The entangled accelerating universe
Pedro F. González-Díaz, Salvador Robles-Pérez
Using the known result that the nucleation of baby universes in correlated pairs is equivalent to spacetime squeezing, we show in this letter that there exists a T-duality symmetry…
