Quantum corrections to cosmic perturbations for a bouncing background
Héctor Hernández-Hernández, Hugo A. Morales-Técotl, Gustavo Sánchez-Herrera
We compute second-order quantum dispersions and correlations corrections, within an effective framework describing a single scalar perturbation mode propagating on a bouncing Loop…

Singularity removal in a quantum effective evolution of the Mixmaster cosmological model
Héctor Hugo Hernández Hernández, Gustavo Alejandro Sánchez Herrera
In this work we analyze the evolution of the quantum Mixmaster cosmological model within an effective approach. In particular, we study the behaviour of the scale factor and anisot…
