Runaway potentials in warm inflation satisfying the swampland conjectures

TL;DR

This paper demonstrates that warm inflation models with runaway potentials, which align with swampland conjectures, can match current observations and satisfy multiple quantum gravity constraints, making them viable effective field theories.

Contribution

It introduces warm inflation models with cubic temperature-dependent dissipation that satisfy all three key swampland conjectures simultaneously.

Findings

Models are consistent with current observational data.

Models satisfy Swampland Distance, de Sitter, and Trans-Planckian Censorship Conjectures.

Potentially viable from quantum gravity and string theory perspectives.

Abstract

The runaway potentials, which do not possess any critical points, are viable potentials which befit the recently proposed de Sitter swampland conjecture very well. In this work, we embed such potentials in the warm inflation scenario motivated by quantum field theory models generating a dissipation coefficient with a dependence cubic in the temperature. It is demonstrated that such models are able to remain in tune with the present observations and they can also satisfy all the three Swampland conjectures, namely the Swampland Distance conjecture, the de Sitter conjecture and the Transplackian Censorship Conjecture, simultaneously. These features make such models viable from the point of view of effective field theory models in quantum gravity and string theory, away from the Swampland.
