Two flavor massless Schwinger model on a torus at a finite chemical potential

Abstract

We study the thermodynamics of the two flavor massless Schwinger model on a torus at a finite chemical potential. We show that thermodynamic quantities only depend on the isospin chemical potential and there are marked deviations from a free fermion theory.
