# Bouncing Universe with Quintom Matter

## TL;DR

This paper explores bouncing universe models driven by Quintom matter, demonstrating analytical and numerical solutions across three different models to address the Big Bang singularity problem.

## Contribution

It introduces and analyzes three types of Quintom matter models capable of producing a bouncing universe, including phenomenological, two scalar fields, and a modified Born-Infeld scalar field.

## Key findings

- Explicit analytical bouncing solutions are derived.
- Numerical simulations confirm the viability of the models.
- Models successfully cross the cosmological constant boundary.

## Abstract

The bouncing universe provides a possible solution to the Big Bang singularity problem. In this paper we study the bouncing solution in the universe dominated by the Quintom matter with an equation of state (EoS) crossing the cosmological constant boundary. We will show explicitly the analytical and numerical bouncing solutions in three types of models for the Quintom matter with an phenomenological EoS, the two scalar fields and a scalar field with a modified Born-Infeld action.
