Query: On the Inhomogeneous Phase of the Chiral Gross-Neveu Model   There is substantial evidence that the ground state of the 2d chiral
Gross-Neveu model, in the presence of a $U(1)$ fermion number chemical
potential $\mu$ and in the large $N$ limit, is given by a chiral spiral phase,
namely an inhomogeneous phase with a chiral condensate having a spatially
periodic phase. We show that the chiral spiral configuration persists at finite
$N$ for any $\mu>0$. Our analysis is based on non-abelian bosonization, that
relates the model to a $U(N)_1$ WZW model deformed by current-current
interactions. In this description the appearance of the inhomogeneous phase is
surprisingly simple. We also rederive the phase diagram of the large $N$ chiral
Gross-Neveu model via a direct diagrammatic computation, finding agreement with
previous results in the literature.
