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…

Uniqueness of the Fock quantization of scalar fields and processes with signature change in cosmology
Laura Castelló Gomar, Guillermo A. Mena Marugán
We study scalar fields subject to an equation of the Klein-Gordon type in nonstationary spacetimes, such as those found in cosmology, assuming that all the relevant spatial depende…
