Inflation from inhomogeneous polarized Gowdy model
Javier Olmedo
We study polarized Gowdy cosmologies on the three torus coupled to a massive scalar field. The phase space of the model admits a simple splitting between homogeneous and inhomogene…

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…
