Symmetric Pair Plasmas with Impurities and Acoustic Wave in it

TL;DR

This paper investigates how impurities in symmetric pair plasmas enable acoustic waves, which are absent in pure symmetric pair plasmas, providing insights into more complex plasma behaviors.

Contribution

It reveals that impurities such as two-temperature electrons can induce acoustic waves in symmetric pair plasmas, expanding understanding of plasma dynamics with impurities.

Findings

Impurities enable acoustic wave propagation in symmetric pair plasmas.

Pure symmetric pair plasmas lack acoustic waves when both species have the same temperature.

Presence of impurities alters the wave dynamics in pair plasmas.

Abstract

A motivation for the study of symmetric pair plasma dynamics lies in the insight they provide into the dynamics of more general plasmas. In the symmetric pair plasma, when temperature both species is the same, acoustic wave are absent. However in presence other species (impurities) in fullerene pair plasmas. for example two-temperature electrons, acoustic waves are possible.
