Bouncing cosmology in interacting scalar torsion gravity

In this study, we demonstrate the interacting teleparallel gravity models, to describe the matter bounce scenario. We discussed two interacting models and find both are suitable choice to describe the bouncing phenomena. The co-moving Hubble radius, is demonstrated to check the establishment of the matter bounce scenario. All the energy conditions and the behaviour of EoS parameter are analyzed. The violation of NEC at bounce epoch is one of the crucial results used to establish that bouncing behaviour is found to be obeyed. The other energy conditions’ behaviour is in agreement with the EoS parameter which lies in the phantom region at the bounce epoch in both the models.

Abstract

In this study, we demonstrate the interacting teleparallel gravity models, to describe the matter bounce scenario. We discussed two interacting models and find both are suitable choice to describe the bouncing phenomena. The co-moving Hubble radius, is demonstrated to check the establishment of the matter bounce scenario. All the energy conditions and the behaviour of EoS parameter are analyzed. The violation of NEC at bounce epoch is one of the crucial results used to establish that bouncing behaviour is found to be obeyed. The other energy conditions’ behaviour is in agreement with the EoS parameter which lies in the phantom region at the bounce epoch in both the models.
