Bouncing Braneworld with Born-Infeld and Gauss-Bonnet

TL;DR

This paper demonstrates the existence of bouncing cosmological solutions in a braneworld scenario with Born-Infeld and Gauss-Bonnet black holes, leading to a singularity-free universe in classical physics.

Contribution

It introduces new bouncing solutions in braneworld cosmology considering Born-Infeld and Gauss-Bonnet effects, avoiding classical singularities.

Findings

Brane universe avoids zero size in certain parameter ranges

Existence of classical bouncing solutions in the model

Singularity-free cosmology within classical domain

Abstract

We show the existence of some bouncing cosmological solutions in the braneworld scenario. More specifically, we consider a dynamical three-brane in the background of Born-Infeld and electrically charged Gauss-Bonnet black hole. We find that, in certain range of parameter space, the brane universe, at least classically, never shrinks to a zero size, resulting in a singularity-free cosmology within the classical domain.
