Inflation in unimodular loop quantum cosmology
Steffen Gielen, Rita B. Neves
We study inflation in the setting of unimodular loop quantum cosmology, where time evolution is defined in unimodular time rather than with respect to a free, massless scalar field…
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…
Adiabatic renormalization for modified dispersion relations in cosmology
Christian Durán-Romero, Luis J. Garay, Mercedes Martín-Benito +1
We investigate the behavior of scalar quantum fields in cosmological backgrounds under modified dispersion relations, specifically focusing on how ultraviolet asymptotics influence…
