Entangled pairs in evaporating black holes without event horizons
Ivan Agullo, Paula Calizaya Cabrera, Beatriz Elizaga Navascués
Investigations into Hawking radiation often assume a black hole model featuring an event horizon, despite the growing consensus that such causal structures may not exist in nature.…
Hamiltonian formulation and loop quantization of a recent extension of the Kruskal spacetime
Beatriz Elizaga Navascués, Alejandro García-Quismondo, Guillermo A. Mena Marugán
We study the Hamiltonian formulation of the Ashtekar-Olmedo-Singh model for the description of the interior geometry of non-rotating, uncharged black holes. This model incorporates…
Space of solutions of the Ashtekar-Olmedo-Singh effective black hole model
Beatriz Elizaga Navascués, Alejandro García-Quismondo, Guillermo A. Mena Marugán
We consider a general choice of integration constants in the resolution of the dynamical equations derived from a recently proposed effective model that describes black hole spacet…
Uniqueness of the Fock quantization of scalar fields in a Bianchi I cosmology with unitary dynamics
Jerónimo Cortez, Beatriz Elizaga Navascués, Mercedes Martín-Benito +3
The Fock quantization of free scalar fields is subject to an infinite ambiguity when it comes to choosing a set of annihilation and creation operators, choice that is equivalent to…
Dirac fields in flat FLRW cosmology: Uniqueness of the Fock quantization
Jerónimo Cortez, Beatriz Elizaga Navascués, Mercedes Martín-Benito +2
We address the issue of the infinite ambiguity that affects the construction of a Fock quantization of a Dirac field propagating in a cosmological spacetime with flat compact secti…
Modeling effective FRW cosmologies with perfect fluids from states of the hybrid quantum Gowdy model
Beatriz Elizaga Navascués, Mercedes Martín-Benito, Guillermo A. Mena Marugán
We employ recently developed approximation methods in the hybrid quantization of the Gowdy model with linear polarization and a massless scalar field to obtain physically int…
