Energy density, temperature, and entropy dynamics in perturbative reheating
Energy density, temperature, and entropy dynamics in perturbative reheating
We discuss the perturbative decay of the energy density of a nonstandard inflaton field ${\ensuremath{\rho}}_{\ensuremath{\phi}}$ and the corresponding creation of the energy density of the relativistic fields ${\ensuremath{\rho}}_{r}$ at the end of inflation, in the perfect fluid description, refining some concepts and providing some new computations. In particular, the process …
