Monopole Chains in the Compact Abelian Higgs Model with doubly-charged Matter Field

TL;DR

This paper investigates topological monopole chains in a lattice Abelian Higgs model with doubly-charged matter, revealing their role in confinement and string breaking phenomena relevant to non-Abelian gauge theories.

Contribution

It demonstrates the formation of monopole chains in the Q=2 matter field model and links these structures to confinement and string breaking mechanisms.

Findings

Monopoles and antimonopoles form dense chain-like structures in the confinement phase.

These chains explain confinement of single-charged particles and string breaking between doubly-charged test particles.

The results shed light on how non-diagonal gluons could reproduce string breaking in gluodynamics.

Abstract

We study the properties of topological defects in the lattice compact Abelian Higgs Model with charge Q=2 matter field. We find that monopoles and antimonopoles form chain-like structures which are dense in the confinement/symmetric phase. In this phase the mentioned structures explain both the confinement of single-charged and the breaking of strings spanned between doubly-charged test particles. This observation helps to understand how the non-diagonal gluons, once taken into consideration in the Abelian projection of gluodynamics, could reproduce in this framework the string breaking for adjoint charges.
