We study the thermodynamics of the two flavor massless Schwinger model on a torus at a finite chemical potential. We show that the physics only depends on the isospin chemical potential, and there are marked deviations from a free fermion theory. We argue that spatial inhomogeneities can develop in the system at very low temperatures.
