Photon-photon interaction and Schwinger process

TL;DR

This paper investigates photon-photon interactions and the Schwinger process, analyzing tunneling induced by particle collisions, and compares thermal bath and classical approaches while computing Coulomb and Yukawa corrections.

Contribution

It introduces a detailed comparison between thermal and classical methods for photon-photon tunneling processes and calculates relevant Coulomb and Yukawa corrections.

Findings

Thermal and classical approaches yield consistent results.

Coulomb and Yukawa corrections significantly affect the process rate.

Classical configurations effectively reproduce thermal bath results.

Abstract

We consider the tunneling processes induced by two-particle collisions. The result derived by the termal bath approach is reproduced by the classical configurations. The Coulomb and Yukawa corrections for the rate of the process are computed.
