Nonabelian strings in a dense matter

Understand

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.
