The Weakly Coupled Gross-Neveu Model with Wilson Fermions
The nature of the phase transition in the lattice Gross-Neveu model with Wilson fermions is investigated using a new analytical technique. This involves a new type of weak coupling expansion which focuses on the partition function zeroes of the model. Its application to the single flavour Gross-Neveu model yields a phase diagram whose structure is consistent with that predicted from a saddle po...
متن کاملGauged Gross–Neveu model with overlap fermions∗
Institute of Physics, University of Tokyo, Komaba, Tokyo, 153-8902 Japan February 29, 2008 We investigate chiral properties of the overlap lattice fermion by using solvable model in two dimensions, the gauged Gross-Neveu model. In this model, the chiral symmetry is spontaneously broken in the presence of small but finite fermion mass. We calculate the quasi-Nambu-Goldstone(NG) boson mass as a f...
متن کاملTwo–dimensional lattice Gross–Neveu model with Wilson twisted mass fermions
We study the two-dimensional lattice Gross–Neveu model with Wilson twisted mass fermions in order to explore the phase structure in this setup. In particular, we investigate the behaviour of the phase transitions found earlier with standard Wilson fermions as a function of the twisted mass parameter μ. We find that qualitatively the dependence of the phase transitions on μ is very similar to th...
متن کاملLattice Gross-Neveu model with domain-wall fermions∗
We investigate the two-dimensional lattice Gross–Neveu model, using the domain-wall fermion formulation, as a toy model of lattice QCD. We study features of the phase diagram related to the mechanism of chiral symmetry restoration, and find that the parity-broken phase (Aoki phase) exists for finite extent in the extra dimension (Ns). We also find that O(a) scaling violation terms vanishes in t...
متن کاملTwo dimensional lattice Gross–Neveu model with domain-wall fermions
We investigate the two dimensional lattice Gross–Neveu model in large flavor number limit using the domain-wall fermion formulation, as a toy model of lattice QCD. We study nonperturbative behavior of the restoration of chiral symmetry of the domain-wall fermions as the extent of the extra dimension (Ns) is increased to infinity. We find the the parity broken phase (Aoki phase) for finite Ns, a...
