Quasinormal modes in effective loop quantum gravity and consequences for isospectrality
Alejandro García-Quismondo, Guillermo A. Mena Marugán, Alvaro Torres-Caballeros
We investigate the quasinormal mode spectra of axial and polar perturbations about the effective Ashtekar, Olmedo, and Singh black hole geometry within the hybrid approach to loop…
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…
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…
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…
Primordial perturbations in the Dapor-Liegener model of hybrid loop quantum cosmology
Laura Castelló Gomar, Alejandro García-Quismondo, Guillermo A. Mena Marugán
In this work, we extend the formalism of hybrid loop quantum cosmology for primordial perturbations around a flat, homogeneous, and isotropic universe to the new treatment of Fried…
The Martin-Benito-Mena Marugan-Olmedo prescription for the Dapor-Liegener model of Loop Quantum Cosmology
Alejandro García-Quismondo, Guillermo A. Mena Marugán
Recently, an alternative Hamiltonian constraint for Loop Quantum Cosmology has been put forward by Dapor and Liegener, inspired by previous work on regularization due to Thiemann.…
