Mass of cosmological perturbations in the hybrid and dressed metric formalisms of Loop Quantum Cosmology for the Starobinsky and exponential potentials

Simon Iteanu, Guillermo A. Mena Marugán

The hybrid and the dressed metric formalisms for the study of primordial perturbations in Loop Quantum Cosmology lead to dynamical equations for the modes of these perturbations th…

Exploring alternatives to the Hamiltonian calculation of the Ashtekar-Olmedo-Singh black hole solution

Alejandro García-Quismondo, Guillermo A. Mena Marugán

In this article, we reexamine the derivation of the dynamical equations of the Ashtekar-Olmedo-Singh black hole model in order to determine whether it is possible to construct a Ha…

Analytical investigation of pre-inflationary effects in the primordial power spectrum: From General Relativity to hybrid Loop Quantum Cosmology

Beatriz Elizaga Navascués, Guillermo A. Mena Marugán

This work is an analytical study of the main differences between classical inflationary effects of a fast-roll regime and imprints of hybrid Loop Quantum Cosmology (LQC) on the pri…

Hybrid Loop Quantum Cosmology: An Overview

Beatriz Elizaga Navascués, Guillermo A. Mena Marugán

Loop Quantum Gravity is a nonperturbative and background independent program for the quantization of General Relativity. Its underlying formalism has been applied successfully to t…

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…

The time-dependent mass of cosmological perturbations in loop quantum cosmology: Dapor-Liegener regularization

Alejandro García-Quismondo, Guillermo A. Mena Marugán, Gabriel Sánchez Pérez

In this work, we compute the time-dependent masses that govern the dynamics of scalar and tensor perturbations propagating on an effective flat, homogeneous, and isotropic backgrou…
