Nonlinear three wave interaction in pair plasmas

TL;DR

This paper investigates the nonlinear three-wave interactions in pair plasmas, revealing that such interactions impose more restrictive conditions for energy transfer than in electron-ion plasmas.

Contribution

It provides a theoretical analysis showing the differences in energy transfer conditions between pair plasmas and electron-ion plasmas.

Findings

More restrictive conditions for double energy transfer in pair plasmas.

Vector-product type nonlinearities characterize the three-wave interaction.

Differences highlighted compared to electron-ion plasma interactions.

Abstract

It is shown that nonlinear three-wave interaction, described by vector-product type nonlinearities, in pair plasmas implies much more restrictive conditions for a double energy transfer, as compared to electron-ion plasmas.
