Monte-Carlo simulation of the chiral Gross-Neveu model
We investigate the two flavor chiral Gross-Neveu model in the Schrödinger functional on the lattice. The procedure necessary to recover chiral symmetry in the continuum limit of this model with Wilson fermions is discussed. We introduce several useful observables and present a first demonstration of the feasibility of Monte-Carlo simulations in this model. MC simulation of the chiral GN-model T...
متن کاملChiral symmetry restoration of QCD and the Gross-Neveu model
Massless QCD has a flavour singlet, chiral symmetry that is broken spontaneously, but becomes restored at sufficently high temperature. For two flavours the symmetry restoring transition is widely accepted to be of second order. According to arguments first given by Pisarski and Wilczek, the universality class belongs to that of the O(4)spin model in 3d. Beyond others, two main assumptions made...
متن کاملThe Gross-Neveu model and QCDs chiral phase transition
Quantum chromodynamics has a rather complicated phase structure. The finite temperature, chiral phase structure depends on the number of flavours and to a large extent on the particular values of the fermion masses. For two massless flavours there is a true second order transition. It has been argued that this transition belongs to the universality class of the three-dimensional O(4) spin model...
متن کاملGross – Neveu Model
for i = 1, · · · , N . Note that the sum over i is taken inside the parenthes before taking the square, which is not very clear in the way Peskin–Schroeder writes the Lagrangian density. I’ve put the subscript g0 to indicate that it is the bare coupling. This model describes massless spin 1/2 fermions in one spatial dimension with an attractive short-range potential. What the model does is that...
متن کاملUniversality in the Gross - Neveu model
We consider universal finite size effects in the large-N limit of the continuum Gross-Neveu model as well as in its discretized versions with Wilson and with staggered fermions. After extrapolation to zero lattice spacing the lattice results are compared to the continuum values.
