Warm inflation with an oscillatory inflaton in the non-minimal kinetic coupling model

In the cold inflation scenario, the slow roll inflation and reheating via coherent rapid oscillation, are usually considered as two distinct eras. When the slow roll ends, a rapid oscillation phase begins and the inflaton decays to relativistic particles reheating the Universe. In another model dubbed warm inflation, the rapid oscillation phase is suppressed, and we are left with ...

Temperature in warm inflation in non-minimal kinetic coupling model

Warm inflation in the non-minimal derivative coupling model with a general dissipative coefficient is considered. We investigate the conditions for the existence of the slow roll approximation and study cosmological perturbations. The spectral index and the power spectrum are calculated and the temperature of the universe at the end of the slow roll warm inflation is obtained.
