Inflation and late-time acceleration from a double-well potential with cosmological constant

Abstract

A model of a universe without big bang singularity is presented, which displaysanearly inflationary period ending just before a phase transition to a deflationary epoch. The model produces enough heavy particles so as to reheat the universe at temperatures in the MeV regime. After the reheating, it smoothly matches the standard $\Lambda$CDM scenario.
