Non-singular superstring cosmology in two dimensions
Herve Partouche
TL;DR
This paper reviews a new approach to superstring cosmology in two dimensions that avoids traditional singularities and Hagedorn instabilities, providing a stable framework for early universe models.
Contribution
It introduces hybrid models in two dimensions that demonstrate non-singular superstring cosmological evolutions, advancing the understanding of stable early universe scenarios.
Findings
Models are free of Hagedorn instabilities.
Cosmological evolutions are non-singular.
Provides a framework for stable superstring cosmology.
Abstract
We review a recently proposed approach to construct superstring cosmological evolutions, which are free of Hagedorn instabilities and initial singularities. We illustrate these ideas in hybrid models in two dimensions.
