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.

  1. Scaling solutions in quintessential inflation

    gr-qc 2019-08 conditional novelty 5.0 of 10

    In quintessential inflation, the scalar field misses the scaling-solution attractor during radiation, so a single exponential tail can drive both inflation and dark energy.

  2. Modified Gravity Theories on a Nutshell: Inflation, Bounce and Late-time Evolution

    gr-qc 2017-05 accept novelty 2.0 of 10

    Modified gravity theories supply viable mathematical frameworks for inflation, bounces, and dark energy eras that match observational data.
