Determination of the chiral condensate from (2+1)-flavor lattice QCD.

Determination of the Chiral Condensate from (2 p 1)-Flavor Lattice QCD

A new method to measure the chiral condensate in lattice QCD using Wilson fermions

Parity and flavor symmetry is not broken in QCD. Using this fact, we propose a new method to measure the chiral condensate in lattice QCD using Wilson fermions with an operator that breaks parity and flavor in addition to the chiral symmetry. PACS #: 12.38.-t, 11.30.Rd, 11.15.Ha.

The domain wall fermion chiral condensate in quenched QCD

It is a common assertion that quenched lattice QCD qualitatively produces many of the features found in continuum full QCD. However, a quenched simulation is expected to include topological gauge configurations which produce exact fermion zero modes. Not suppressed by the missing fermion determinant, such modes will cause divergent behavior in the small mass limit of the chiral condensate. Surp...

We investigate the finite-temperature phase structure and the scaling of the chiral condensate in lattice QCD with two degenerate light quarks, using a renormalization group improved gauge action and the Wilson quark action. We obtain a phase diagram which is consistent with that from the parity-flavor breaking scenario. The scaling relation for the chiral condensate assuming the critical expon...

We study the strong coupling limit of the one-flavor and two-flavor massless 't Hooft models, large − N c-color QCD 2 , on a lattice. We use staggered fermions and the Hamiltonian approach to lattice gauge theories. We show that the one-flavor model is effectively described by the antiferro-magnetic Ising model, whose ground state is the vacuum of the gauge model in the infinite coupling limit;...
