Mirror mode junctions as sources of radiation

TL;DR

This paper explores how mirror mode structures in collisionless plasmas can act as quasi-superconductors, emitting weak electromagnetic radiation in specific frequency ranges due to their unique magnetic and electron dynamics.

Contribution

It introduces a semi-classical model for mirror mode phase transitions and predicts electromagnetic radiation emission from mirror perforated plasmas based on Josephson conditions.

Findings

Mirror modes behave as quasi-superconductors with phase transition conditions.

Mirror perforated plasmas emit weak electromagnetic radiation in sub-millimeter and infrared ranges.

The model links plasma magnetic textures to electromagnetic emission phenomena.

Abstract

Mirror modes in collisionless high-temperature plasmas represent macroscopic high-temperature quasi-superconductors with bouncing electrons in discrete-particle resonance with thermal ion-sound noise contributing to the ion-mode growth beyond quasilinear stability. In the semi-classical GL approximation the conditions for phase transition are given. The quasi-superconducting state is of second kind causing a magnetically perforated plasma texture. Focussing on the interaction of mirror bubbles we apply semi-classical Josephson conditions and show that a mirror perforated plasma emits weak electromagnetic radiation which in the magnetosheath is in the sub-millimeter respectively infrared range.
