String Gases and the Swampland

TL;DR

This paper explores how string gases can stabilize moduli in string theory, satisfying the de Sitter conjecture and leading to gravity as the weakest force, within the Swampland framework.

Contribution

It introduces a framework where string gases produce a potential that stabilizes moduli at the self-dual radius and complies with Swampland conjectures.

Findings

Moduli stabilized at the self-dual radius.

Potential satisfies the de Sitter conjecture.

Gravity emerges as the weakest force.

Abstract

In this paper, we study some aspects of moduli stabilization using string gases in the context of the Swampland. In the framework which we derive, the matter Lagrangian for string gases yields a potential for the size moduli which satisfies the de Sitter conjecture with the condition $\frac{|\nabla V|}{V} \geq \frac{1}{\sqrt{p}}\frac{1}{M_p}$, where $p$ is the number of compactified dimensions. Moreover, the moduli find themselves stabilized at the self-dual radius, and gravity naturally emerges as the weakest force.
