Strings And Dyonic Plasmas

TL;DR

This paper extends dual string solutions in ideal Magnetohydrodynamics to plasmas with dyons, which carry both electric and magnetic charges, highlighting differences from purely electric or magnetic plasmas.

Contribution

It introduces dyonic string solutions in MHD, expanding the understanding of plasma behaviors with combined electric and magnetic charges.

Findings

Dyonic plasmas exhibit unique flux configurations.

The ideal approximation's validity varies between electric, magnetic, and dyonic plasmas.

Extended solutions reveal new physical features of dyonic systems.

Abstract

Recently Olesen has shown the existence of dual string solutions to the equations of ideal Magnetohydrodynamics that describe the long wavelength properties of electrically charged plasmas. Here, we extend these solutions to include the case of plasmas consisting of point like dyons, which carry both electric and magnetic charge. Such strings are dyonic in that they consist of both magnetic and electric flux. We contrast some physical features of dyonic plasmas with those of the purely electric or magnetic type, particularly in relation to the validity of the ideal approximation.
