Cosmological perturbations in Hybrid Loop Quantum Cosmology: Mukhanov-Sasaki variables
Laura Castelló Gomar, Mikel Fernández-Méndez, Guillermo A. Mena Marugán +1
We study cosmological perturbations in the framework of Loop Quantum Cosmology, using a hybrid quantization approach and Mukhanov-Sasaki variables. The formulation in terms of thes…
Effective dynamics of scalar perturbations in a flat Friedmann-Robertson-Walker spacetime in Loop Quantum Cosmology
Mikel Fernández-Méndez, Guillermo A. Mena Marugán, Javier Olmedo
We study the evolution of a homogeneous and isotropic spacetime whose spatial sections have three-torus topology, coupled to a massless scalar field with small scalar perturbations…
Singularity avoidance in the hybrid quantization of the Gowdy model
Paula Tarrío, Mikel Fernández-Méndez, Guillermo A. Mena Marugán
One of the most remarkable phenomena in Loop Quantum Cosmology is that, at least for homogeneous cosmological models, the Big Bang is replaced with a Big Bounce that connects our u…
Hybrid quantization of an inflationary model: The flat case
Mikel Fernández-Méndez, Guillermo A. Mena Marugán, Javier Olmedo
We present a complete quantization of an approximately homogeneous and isotropic universe with small scalar perturbations. We consider the case in which the matter content is a min…
A complete hybrid quantization in inhomogeneous cosmology
Mikel Fernández-Méndez, Guillermo A. Mena Marugán, Javier Olmedo
A complete quantization of a homogeneous and isotropic spacetime with closed spatial sections coupled to a massive scalar field is provided, within the framework of Loop Quantum Co…
Hybrid quantization of an inflationary universe
Mikel Fernández-Méndez, Guillermo A. Mena Marugán, Javier Olmedo
We quantize to completion an inflationary universe with small inhomogeneities in the framework of loop quantum cosmology. The homogeneous setting consists of a massive scalar field…
Unique Fock quantization of scalar cosmological perturbations
Mikel Fernández-Méndez, Guillermo A. Mena Marugán, Javier Olmedo +1
We investigate the ambiguities in the Fock quantization of the scalar perturbations of a Friedmann-Lemaître-Robertson-Walker model with a massive scalar field as matter content. We…
