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…
Asymptotic regularization method. A constructive approach
Christian Durán Romero, Luis J. Garay, Mercedes Martín-Benito +1
We introduce a new regularization scheme for divergent integrals in quantum field theory. The framework is based on the structural decomposition of the integrand asymptotic expansi…
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…
