Non-oscillatory power spectrum from States of Low Energy in kinetically dominated early universes
Mercedes Martín-Benito, Rita B. Neves, Javier Olmedo
Recently, States of Low Energy (SLEs) have been proposed as viable vacuum states of primordial perturbations within Loop Quantum Cosmology (LQC). In this work we investigate the ef…
States of Low Energy in bouncing inflationary scenarios in Loop Quantum Cosmology
Mercedes Martín-Benito, Rita B. Neves, Javier Olmedo
In generic Friedmann-Lemaître-Robertson-Walker spacetimes, States of Low Energy (SLEs) are defined to minimize the regularized energy density smeared along the time-like curve of a…
The Effect of a positive cosmological constant on the bounce of Loop Quantum Cosmology
Mercedes Martín-Benito, Rita B. Neves
We provide an analytical solution to the quantum dynamics of a flat Friedmann-Lemaître- Robertson-Walker model with a massless scalar field in the presence of a small and positive…
Unitary quantization of a charged scalar field and Schwinger effect
Luis J. Garay, Alberto García Martín-Caro, Mercedes Martín-Benito
Quantum field theory in curved spacetimes suffers in general from an infinite ambiguity in the choice of Fock representation and associated vacuum. In cosmological backgrounds, the…
Solvable Loop Quantum Cosmology: domain of the volume observable and semiclassical states
Mercedes Martín-Benito, Rita B. Neves
The dynamics of a flat Friedmann-Lemaître-Robertson-Walker model minimally coupled to a massless scalar field has been intensively studied in the context of Loop Quantum Cosmology.…
On the Uniqueness of the Fock Quantization of the Dirac Field in the Closed FRW Cosmology
Jerónimo Cortez, Ilda Inácio Rodrigues, Mercedes Martín-Benito +1
The Fock quantization of free fields propagating in cosmological backgrounds is in general not unambiguously defined due to the non-stationarity of the spacetime. For the case of a…
