Nonabelian strings in a dense matter

TL;DR

This paper explores how chemical potential influences gauge theories with scalar matter, leading to the formation of nonabelian non-BPS strings in dense matter, and discusses the associated worldsheet theory.

Contribution

It demonstrates that chemical potential acts like an FI term, enabling the existence of nonabelian non-BPS strings in dense matter within weak coupling regimes.

Findings

Chemical potential mimics FI term effects.

Nonabelian non-BPS strings are supported at high chemical potential.

Brief discussion of worldsheet theory on these strings.

Abstract

We consider gauge theories with scalar matter with and without supersymmetry at nonzero chemical potential. It is argued that a chemical potential plays a role similar to the FI term. We analyze theory at weak coupling regime at large chemical potential and argue that it supports nonabelian non-BPS strings. Worldsheet theory on the nonabelian string in a dense matter is briefly discussed.
