Warm inflation as a way out of the swampland

TL;DR

This paper explores how warm inflation, characterized by dissipative effects and a thermal bath, can potentially evade Swampland conjectures, offering a viable inflationary model consistent with quantum gravity constraints.

Contribution

It analyzes various dissipation mechanisms in warm inflation and demonstrates their potential to bypass Swampland constraints, bridging microphysical models with cosmological viability.

Findings

Dissipative effects can help warm inflation evade Swampland conjectures.

Different dissipation forms are viable within microphysical and phenomenological frameworks.

Warm inflation offers a consistent alternative to standard models under Swampland criteria.

Abstract

We discuss how dissipative effects and the presence of a thermal radiation bath, which are inherent characteristics of the warm inflation dynamics, can evade the recently proposed Swampland conjectures. Different forms of dissipation terms, motivated by both microphysical quantum field theory and phenomenological models, are discussed and their viability to overcome the assumed Swampland constraints is analyzed.
