Renormalization effects fade away during inflation
Christian Durán Romero, Luis J. Garay, Mercedes MartÃn-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…

Estimation of gravitational production uncertainties
Jose A. R. Cembranos, Luis J. Garay, Ãlvaro Parra-López +1
Cosmological production of scalar, non-minimally coupled dark matter depends on the specifics of the inflationary model under consideration. We analyze both Starobinsky inflation a…

Influence of spatial curvature in cosmological particle production
Jose A. R. Cembranos, Luis J. Garay, Ãlvaro Parra-López
We analyze cosmological particle production driven by spacetime expansion in the early universe for homogeneous and isotropic cosmologies with positive, negative, and zero spatial…
