# Asymmetric nonsingular bounce from a dynamic scalar field

## TL;DR

This paper introduces a scalar-field model that achieves a nonsingular cosmological bounce with time asymmetry and a change in the equation-of-state after the bounce, providing a novel approach to early universe modeling.

## Contribution

It proposes a new scalar-field model with a time-reversal-noninvariant potential that realizes a dynamic, asymmetric nonsingular bounce with post-bounce equation-of-state change.

## Key findings

- Demonstrates a viable scalar-field bounce model
- Shows the model's ability to produce a time-asymmetric bounce
- Highlights the change in effective equation-of-state after the bounce

## Abstract

We present a dynamical model for a time-asymmetric nonsingular bounce with a post-bounce change of the effective equation-of-state parameter. Specifically, we consider a scalar-field model with a time-reversal-noninvariant effective potential.
