Large N QCD in two dimensions with a baryonic chemical potential

TL;DR

This paper investigates large N QCD in two dimensions with a baryonic chemical potential, demonstrating that no phase transition occurs as the chemical potential varies, supported by analytical and numerical evidence.

Contribution

It shows that reduction holds in large N two-dimensional QCD with a chemical potential, and finds no phase transition across the chemical potential range.

Findings

Reduction persists with chemical potential.

No phase transition observed as chemical potential varies.

Analytical and numerical results are consistent.

Abstract

We consider large N gauge theory on a two dimensional lattice in the presence of a baryonic chemical potential. We work with one copy of naive fermion and argue that reduction holds even in the presence of a chemical potential. Analytical arguments supported by numerical studies show that there is no phase transition as a function of the baryonic chemical potential.
