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.…
Fock quantization of a Klein-Gordon field in the interior geometry of a nonrotating black hole
Jerónimo Cortez, Beatriz Elizaga Navascués, Guillermo A. Mena Marugán +2
We study the canonical quantization of a scalar field in a Kantowski-Sachs spacetime. For simplicity, we consider compactified spatial sections, since this does not affect the ultr…
Effects of the inflaton potential on the primordial power spectrum in Loop Quantum Cosmology scenarios
Beatriz Elizaga Navascués, Guillermo A. Mena Marugán, Jesús Yébana Carrilero
In scenarios of physical interest in Loop Quantum Cosmology, with a preinflationary epoch where the kinetic energy of the inflaton dominates, the analytic study of the dynamics of…
Extended phase space quantization of a black hole interior model in Loop Quantum Cosmology
Beatriz Elizaga Navascués, Guillermo A. Mena Marugán, Andrés Mínguez Sánchez
Considerable attention has been paid to the study of the quantum geometry of nonrotating black holes within the framework of Loop Quantum Cosmology. This interest has been reinvigo…
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…
Primordial perturbations in kinetically dominated regimes of general relativity and hybrid quantum cosmology
Beatriz Elizaga Navascués, Rafael Jiménez-Llamas, Guillermo A. Mena Marugán
Scalar fields with an energy density dominated by its kinetic part may have played a relevant role in the very early stages of the Universe. Compared to the standard inflationary p…
Quantization ambiguities and the robustness of effective descriptions of primordial perturbations in hybrid Loop Quantum Cosmology
Beatriz Elizaga Navascués, Guillermo A. Mena Marugán
We study the imprint that certain quantization ambiguities may leave in effective regimes of the hybrid loop quantum description of cosmological perturbations. More specifically, i…
