Self-T-Dual Brane Cosmology

TL;DR

This paper explores how T-duality can be applied to brane cosmology, resulting in a bouncing universe model and a self-tuning static solution, offering new insights into early universe scenarios.

Contribution

It demonstrates the implementation of T-duality in brane cosmology, leading to novel bouncing and static solutions with self-tuning properties.

Findings

Achieved a smooth bouncing cosmology similar to pre-Big Bang models.

Discovered a static self-tuning solution via T-duality along time.

Showed T-duality can be incorporated into brane cosmology frameworks.

Abstract

We show how T-duality can be implemented with brane cosmology. As a result, we obtain a smooth bouncing cosmology with features similar to the ones of the pre-Big Bang scenario. Also, by allowing T-duality transformations along the time-like direction, we find a static solution that displays an interesting self tuning property.
