# Quantum Evaporation of Classical Breathers

## TL;DR

This paper investigates the quantum evaporation of classical breathers using the classical-quantum correspondence, providing numerical analysis of decay rates and accounting for quantum backreaction on classical oscillons.

## Contribution

It introduces a novel application of the classical-quantum correspondence to study breather decay and quantum backreaction in an extended sine-Gordon model.

## Key findings

- Decay rate varies with coupling strength.
- Quantum backreaction significantly affects breather dynamics.
- Numerical results demonstrate the quantum evaporation process.

## Abstract

We apply the recently discovered classical-quantum correspondence (CQC) to study the quantum evaporation of breathers in an extended sine-Gordon model. We present numerical results for the decay rate of the breather as a function of the coupling strength in the model. This is a complete treatment of the backreaction of quantum radiation on the classical dynamics of oscillons.
