GROSS–NEVEU MODEL WITH OVERLAP FERMIONS
GROSS–NEVEU MODEL WITH OVERLAP FERMIONS
We investigate the chiral properties of overlap lattice fermion by using two dimensional Gross-Neveu model coupled with a gauge field. Chiral properties of this model are similar to those of QCD$_4$, that is, the chiral symmetry is spontaneously broken in the presence of small but finite fermion mass and also …
