Inhomogeneous Phases at Finite Flavor Numbers in 2D Gross-Neveu Models — •Julian Lenz1, Laurin Pannullo2, Marc Wagner2, Björn Wellegehausen1, and Andreas Wipf1 — 1Theoretisch-Physikalisches Institut, FSU Jena — 2Institut für theoretische Physik, Universtiät Frankfurt
In the limit of infinite number of flavors Nf the Gross-Neveu model in two dimensions becomes solvable analytically. About 15 years ago Thies et al. found inhomogeneous phases for non-vanishing chemical potential in that limit and since then a revisited phase diagram for infinite Nf was established. However, for a long time it was unclear if this is an artifact of the infinite flavor number or survives the transition to finite Nf. We present lattice Monte-Carlo results that indicate the existence of inhomogeneous condensates for all (even) flavor numbers Nf.
