Influence of spatial curvature in cosmological particle production
Jose A. R. Cembranos, Luis J. Garay, Álvaro 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…

Estimation of gravitational production uncertainties
Jose A. R. Cembranos, Luis J. Garay, Álvaro 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…
