Reheating and particle creation in unimodular f(R, T) gravity

Abstract: We study cosmological inflation and reheating in the unimodular f (R, T ) gravity. During the reheating era, which takes place just after the end of inflation, the energy density of inflaton is converted to radiation energy through, for instance, rapid oscillation about the minimum of the potential. We quantify our investigation by calculating the reheating temperature. This quantity is written in terms of the spectral index and the power spectrum, which provides a suitable framework to constrain the parameter… Show more
