Anomalous pinch of turbulent plasmas driven by the magnetic-drift-induced Lorentz force through the Stokes-Einstein relation

TL;DR

This paper reveals that the magnetic drift-induced Lorentz force causes a universal plasma pinch effect on particles, energy, and momentum, explained through a theoretical model based on the Stokes-Einstein relation, applicable to various plasma particles.

Contribution

It introduces a novel theoretical framework linking magnetic drift Lorentz force to plasma pinch fluxes via the Stokes-Einstein relation, applicable to multiple particle types.

Findings

Lorentz force drives plasma pinch fluxes of particles, energy, and momentum.

The model applies to electrons, ions, trapped, and passing particles.

Universal plasma pinch effect explained through the proposed theory.

Abstract

It is found that the Lorentz force generated by the magnetic drift drives a generic plasma pinch fluxes of particle, energy and momentum through the Stokes-Einstein relation. The proposed theoretical model applies for both electrons and ions, trapped particles and passing particles.
