Nonlinear theory of intense laser-plasma interactions modified by vacuum-polarization effects

TL;DR

This paper extends classical nonlinear laser-plasma interaction theory by incorporating vacuum polarization effects from quantum electrodynamics, leading to a more accurate model for extreme laser and high-energy-density plasma interactions.

Contribution

It introduces a modified wave equation derived from the Heisenberg-Euler Lagrangian that accounts for vacuum polarization effects in intense laser-plasma interactions.

Findings

Vacuum polarization significantly alters laser-plasma interaction dynamics.

Enhanced effects of vacuum polarization are demonstrated.

A new model better describes extreme laser and plasma interactions.

Abstract

The classical nonlinear laser-plasma interaction theory is corrected. Given the effects of vacuum polarization (induced by extreme laser) as nonlinear media response, one-dimensional wave equations of a monochromatic laser field are derived from the Heisenberg-Euler Lagrangian density and a derivative correction with the first order quantum electrodynamic (QED) effects. A more suitable model to formulate the interactions of extreme laser and high-energy-density plasma is developed. In the results, the enhanced effect of vacuum polarization will be discussed and shown.
