TL;DR

This paper numerically investigates the Emergent Cyclic Inflation scenario, which features a universe expanding through multiple asymmetric cycles driven by entropy production, offering a nonsingular, geodesically complete model without reheating.

Contribution

It provides the first comprehensive numerical analysis of the Emergent Cyclic Inflation scenario, highlighting its unique features and viability as an alternative to traditional inflation models.

Findings

Universe expands via multiple asymmetric cycles

Scenario is nonsingular and geodesically complete

No reheating mechanism needed

Abstract

We provide a comprehensive numerical study of the Emergent Cyclic Inflation scenario. This is a scenario where instead of traditional monotonic slow roll inflation, the universe expands over numerous short asymmetric cycles due to the production of entropy via interactions among different species. This is one of the very few scenarios of inflation which provides a nonsingular geodesically complete space-time and does not require any "reheating" mechanism.
