Note on Shape Moduli Stabilization, String Gas Cosmology and the Swampland Criteria

TL;DR

This paper demonstrates that in String Gas Cosmology, the stabilization of shape moduli naturally aligns with the swampland criteria, specifically satisfying the de Sitter conjecture, thus supporting the consistency of these models with string theory.

Contribution

It provides an explicit calculation showing shape moduli stabilization in String Gas Cosmology obeys the swampland de Sitter conjecture, linking cosmological models with string theory constraints.

Findings

Shape moduli are stabilized by string winding and momentum modes.

The effective potential satisfies the de Sitter swampland conjecture.

Supports the viability of String Gas Cosmology within string theory constraints.

Abstract

In String Gas Cosmology, the simplest shape modulus fields are naturally stabilized by taking into account the presence of string winding and momentum modes. We determine the resulting effective potential for these fields and show that it obeys the de Sitter conjecture, one of the swampland criteria for effective field theories to be consistent with superstring theory.
