Interaction of Magnetic Monopoles and Domain Walls

TL;DR

This paper investigates how magnetic monopoles interact with domain walls in a specific symmetry model, revealing that monopoles unwind and release their magnetic energy upon collision with domain walls where symmetry is restored.

Contribution

It provides a numerical study of monopole-domain wall interactions in an SU(5)×Z_2 symmetric model, showing monopole unwinding and energy dissipation.

Findings

Monopoles unwind upon collision with domain walls.

Magnetic energy is dissipated during interaction.

Full SU(5) symmetry is restored inside domain walls.

Abstract

We study the interaction of magnetic monopoles and domain walls in a model with SU(5)\times Z_2 symmetry by numerically evolving the field equations. We find that the monopoles unwind and dissipate their magnetic energy on collision with domain walls within which the full SU(5) symmetry is restored.
