Quantization of the massless scalar field in de Sitter spacetime with unitary dynamics
Jeronimo Cortez, Daniel Martin-de Blas, Guillermo A. Mena Marugan +1
We present a Fock quantization with unitary dynamics for the massless scalar field in de Sitter spacetime.
Uniqueness of the Fock quantization of fields with unitary dynamics in nonstationary spacetimes
Jeronimo Cortez, Guillermo A. Mena Marugan, Javier Olmedo +1
The Fock quantization of fields propagating in cosmological spacetimes is not uniquely determined because of several reasons. Apart from the ambiguity in the choice of the quantum…
A Brief Introduction to Loop Quantum Cosmology
Guillermo A. Mena Marugan
In recent years, Loop Quantum Gravity has emerged as a solid candidate for a nonperturbative quantum theory of General Relativity. It is a background independent theory based on a…
Hybrid Quantum Cosmology: Combining Loop and Fock Quantizations
Guillermo A. Mena Marugan, Mercedes Martin-Benito
As a necessary step towards the extraction of realistic results from Loop Quantum Cosmology, we analyze the physical consequences of including inhomogeneities. We consider in detai…
Physical evolution in Loop Quantum Cosmology: The example of vacuum Bianchi I
Mercedes Martin-Benito, Guillermo A. Mena Marugan, Tomasz Pawlowski
We use the vacuum Bianchi I model as an example to investigate the concept of physical evolution in Loop Quantum Cosmology (LQC) in the absence of the massless scalar field which h…
Loop Quantization of Vacuum Bianchi I Cosmology
M. Martin-Benito, G. A. Mena Marugan, T. Pawlowski
We analyze the loop quantization of the family of vacuum Bianchi I spacetimes, a gravitational system whose classical solutions describe homogeneous anisotropic cosmologies. We rig…
