Lattice Gross-Neveu model with domain-wall fermions

Abstract: We investigate the two dimensional lattice Gross-Neveu model in large $N$ limit on the domain-wall fermions, as the toy model of lattice QCD on domain-wall fermions, in order that we discuss the structure of the domain-wall QCD when the extent of the extra dimension $(N_s)$ is finite. In particular, the necessity of the fine tuning, the existence of the parity-flavor broken phase (Aoki phase), and the structure of the chiral phase boundary are investigated in $N_s$ finite and infinite both.
