Wave Localization and Density Bunching in Pair Ion Plasmas

TL;DR

This paper explores how high-intensity electromagnetic waves can create localized structures in pair ion plasmas with slight asymmetry, potentially informing early universe structure formation.

Contribution

It demonstrates that symmetry-breaking in pair ion plasmas enables electromagnetic wave localization and density bunching, a novel insight into plasma behavior.

Findings

Electromagnetic waves can localize and bunch in asymmetric pair ion plasmas.

Localized density excess occurs in regions of wave localization.

Potential implications for understanding early universe structure formation.

Abstract

By investigating the nonlinear propagation of high intensity electromagnetic (EM) waves in a pair ion plasma, whose symmetry is broken via contamination by a small fraction of high mass immobile ions, it is shown that this new and interesting state of (laboratory created) matter is capable of supporting structures that strongly localize and bunch the EM radiation with density excess in the region of localization. Testing of this prediction in controlled laboratory experiments can lend credence, inter alia, to conjectures on structure formation (via the same mechanism) in the MEV era of the early universe.
