Query: Two-dimensional Lattice Gross-Neveu Model with Wilson Fermion Action at
  Finite Temperature and Chemical Potential   We investigate the phase structure of the two-dimensional lattice Gross-Neveu
model formulated with the Wilson fermion action to leading order of 1/N
expansion. Structural change of the parity-broken phase under the influence of
finite temperature and chemical potential is studied. The connection between
the lattice phase structure and the chiral phase transition of the continuum
theory is clarified.
