Finite temperature QCD phase transition with domain wall fermions - art. no. 014503

The domain wall formulation of lattice fermions is expected to support accu rate chiral symmetry, even at finite lattice spacing. Here we attempt to us e this new fermion formulation to simulate two-flavor, finite temperature Q CD near the chiral phase transition. In this initial study, a variety of qu ark masses, domain wall heights and domain wall separations are explored us ing an 8(3)x4 lattice. Both the expectation value of the Wilson line and th e chiral condensate show the temperature dependence expected for the QCD ph ase transition. Further, the desired chiral properties are seen for the chi ral condensate, suggesting that the domain wall Fermion formulation may be an effective approach for the numerical study of QCD at finite temperature.
