Magnetic monopole in a chiral plasma: chiral dyon

TL;DR

This paper explores how magnetic monopoles interact with chiral plasmas, leading to the formation of a 'chiral dyon' with unique charge properties, which could impact early Universe physics and detection methods.

Contribution

It introduces the concept of a chiral dyon, a monopole dressed with charge due to chiral effects, and analyzes its stationary states in a chiral plasma.

Findings

Monopoles acquire electric charge proportional to chiral density.

Stationary states balance electric and axial currents with the chiral anomaly.

Chiral effects influence monopole evolution and potential detection in the early Universe.

Abstract

The placement of a magnetic monopole into an electrically-neutral chiral plasma with a non-zero axial density results in an electric polarization of the matter. The electric current produced by the chiral magnetic effect is balanced by charge diffusion and Ohmic dissipation, which generates a non-trivial charge distribution. In turn, the latter induces a separation of chiralities along the magnetic field of the monopole due to the chiral separation effect. We find the stationary states of such a system, with vanishing total electric current and stationary axial current balanced by the chiral anomaly. In this solution, the monopole becomes "dressed" with an electric charge that is proportional to the averaged chiral density of the matter -- forming a chiral dyon. The interplay between the chiral effects on the one hand, and presence of magnetic field of the monopole on the other, may affect the evolution of the monopole density in the early Universe, contribute to the process of baryogenesis, and can also be instrumental for detection of relic monopoles using chiral materials.
