Time-dependent scalings and Fock quantization of a massless scalar field in Kantowski-Sachs
Jerónimo Cortez, Guillermo A. Mena Marugán, Alvaro Torres-Caballeros +1
We address the issue of inequivalent Fock representations in Quantum Field Theory in a curved homogenous and anisotropic background, namely Kantowski-Sachs spacetime. A family of u…
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…
A Brief Overview of Results about Uniqueness of the Quantization in Cosmology
Jerónimo Cortez, Guillermo A. Mena Marugán, José M. Velhinho
The purpose of this review is to provide a brief overview of some recent conceptual developments about possible criteria to guarantee the uniqueness of the quantization in a variet…
Uniqueness Criteria for the Fock Quantization of Dirac Fields and Applications in Hybrid Loop Quantum Cosmology
Jerónimo Cortez, Beatriz Elizaga Navascués, Guillermo A. Mena Marugán +2
In generic curved spacetimes, the unavailability of a natural choice of vacuum state introduces a serious ambiguity in the Fock quantization of fields. In this review, we study the…
Quantum linear scalar fields with time dependent potentials: Overview and applications to cosmology
Jerónimo Cortez, Guillermo A. Mena Marugán, José Velhinho
In this work, we present an overview of uniqueness results derived in recent years for the quantization of Gowdy cosmological models and for (test) Klein-Gordon fields minimally co…
On the Uniqueness of the Fock Quantization of the Dirac Field in the Closed FRW Cosmology
Jerónimo Cortez, Ilda Inácio Rodrigues, Mercedes Martín-Benito +1
The Fock quantization of free fields propagating in cosmological backgrounds is in general not unambiguously defined due to the non-stationarity of the spacetime. For the case of a…
