Quantum unitary dynamics of a charged fermionic field and Schwinger effect
Álvaro Álvarez-Domínguez, Luis J. Garay, David García-Heredia +1
In quantum field theory, particle creation occurs, in general, when an intense external field, such as an electromagnetic field, breaks time translational invariance. This leads to…
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…
