Renormalization effects fade away during inflation

Christian Durán Romero, Luis J. Garay, Mercedes Martín-Benito +1

The renormalization of the primordial inflationary power spectrum has long raised the possibility that ultraviolet effects could significantly alter predictions for cosmological ob…

Alleviation of anomalies from the non-oscillatory vacuum in loop quantum cosmology

Mercedes Martín-Benito, Rita B. Neves, Javier Olmedo

In this work we investigate observational signatures of a primordial power spectrum with exponential infrared suppression, motivated by the choice of a non-oscillatory vacuum in a…

States of low energy in the Schwinger effect

Álvaro Álvarez-Domínguez, Luis J. Garay, Mercedes Martín-Benito +1

States of low energy in cosmology minimise the energy density when smeared in a chosen time interval. We extend such construction to generic homogeneous (possibly anisotropic) part…

Operational realization of quantum vacuum ambiguities

Álvaro Álvarez-Domínguez, José A. R. Cembranos, Luis J. Garay +3

We provide a reinterpretation of the quantum vacuum ambiguities that one encounters when studying particle creation phenomena due to an external and time-dependent agent. We propos…

Inhomogenous loop quantum cosmology with matter

Daniel Martín-de Blas, Mercedes Martín-Benito, Guillermo A. Mena Marugán

The linearly polarized Gowdy model with a massless scalar field with the same symmetries as the metric is quantized by applying a hybrid approach. The homogeneous geometry de…
