Interaction Energies of Generalised Monopoles

TL;DR

This paper numerically investigates generalized monopoles in SO(3) gauged Higgs models with Skyrme-like terms, revealing diverse interaction behaviors such as attraction, repulsion, or both among like monopoles.

Contribution

It introduces and analyzes new monopole models that exhibit varied interaction types, expanding understanding of monopole dynamics beyond classical cases.

Findings

Monopoles can exhibit repulsion, attraction, or both, depending on model parameters.

Numerical solutions demonstrate the existence of these generalized monopoles.

The models incorporate Skyrme-like terms to support diverse interaction behaviors.

Abstract

Generalisations of the 't Hooft-Polyakov monopole which can exhibit repulsion only, attraction only, and both attraction and repulsion, between like monopoles, are studied numerically. The models supporting these solitons are SO(3) gauged Higgs models featuring Skyrme-like terms.
