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

TL;DR

This paper investigates the thermodynamics of the two-flavor massless Schwinger model on a torus at finite chemical potential, revealing dependence on isospin chemical potential and deviations from free fermion behavior.

Contribution

It provides a detailed analysis of the model's thermodynamics at finite chemical potential, highlighting non-trivial effects absent in free fermion theories.

Findings

Thermodynamic quantities depend solely on isospin chemical potential.

Significant deviations from free fermion theory are observed.

The model exhibits unique thermodynamic behavior on a torus at 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.
