Warm Inflation

TL;DR

Assuming a first order phase transition during inflation, a model scenario is described which does not require a tiny coupling constant and thermal equilibrium is closely maintained as inflation commences.

Abstract

Assuming a first order phase transition during inflation, a model scenario is described which does not require a tiny coupling constant. Thermal equilibrium is closely maintained as inflation commences. No large scale reheating is necessary. Solutions for $N> 70$ are found for any $δρ/ ρ$ in the range $10^{-5} - 10^{-3}$.
