## TL;DR

This paper explores bouncing cosmology within interacting scalar-torsion gravity models, demonstrating their viability for matter bounce scenarios through analysis of energy conditions and the EoS parameter.

## Contribution

It introduces two interacting teleparallel gravity models capable of describing matter bounce phenomena, with detailed analysis of energy conditions and bounce dynamics.

## Key findings

- Both models successfully describe bouncing behavior.
- NEC violation at bounce epoch confirms the bounce.
- EoS parameter in phantom region during bounce.

## 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 is analysed. The violation of NEC at bounce epoch is one of the crucial result to establish 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.
