Gravitons production in a new type of GCG

TL;DR

This paper proposes a novel early Universe model featuring a smooth transition from a de Sitter-like phase to radiation dominance and calculates the resulting graviton production.

Contribution

It introduces a new cosmological scenario and provides calculations for graviton production within this framework.

Findings

Graviton production is significant during the transition.

The model offers a new perspective on early Universe dynamics.

Potential implications for gravitational wave observations.

Abstract

A new scenario for the early era of the Universe is proposed. It corresponds to a smooth transition between a de Sitter-like phase and a radiation dominated era. We calculate the production of gravitons in this model.
