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…
