TL;DR

This paper investigates how turbulence affects the polarization and stability of ultrarelativistic QED plasma, revealing conditions for instabilities and modifications in plasmon dispersion relations due to turbulent effects.

Contribution

It provides a novel analysis of turbulent Landau damping and its role in plasma instabilities and dispersion relation modifications in ultrarelativistic QED plasma.

Findings

Sign of nonlinear turbulent Landau damping indicates potential instabilities.

Large turbulent fields can cause actual system instabilities.

Turbulence modifies plasmon dispersion relations.

Abstract

Polarization properties of turbulent stochastically inhomogeneous ultrarelativistic QED plasma are studied. It is shown that the sign of nonlinear turbulent Landau damping corresponds to an instability of the spacelike modes and, for sufficiently large turbulent fields, to an actual instability of a system. Modification of plasmon dispersion relations due to turbulent effects are studied.
