Stabilization of Extra Dimensions at Tree Level

TL;DR

This paper proposes a mechanism where string winding and momentum modes stabilize six extra dimensions at the self-dual radius, allowing three dimensions to expand, thus addressing the stabilization problem in string cosmology.

Contribution

It introduces a novel method leveraging string modes to naturally stabilize extra dimensions at the self-dual radius during cosmological evolution.

Findings

Six dimensions stabilize at the self-dual radius

Three dimensions grow large naturally

String modes drive dimensional stabilization

Abstract

By considering the effects of string winding and momentum modes on a time dependent background, we find a method by which six compact dimensions become stabilized naturally at the self-dual radius while three dimensions grow large.
