Ginsparg-Wilson fermion propagators and chiral condensate - art. no. 034503.

By exploiting chiral symmetry, we derive analytic formulas far the massless and the massive Ginsparg-Wilson fermion propagators. Using these formulas, we derive an expression for the chiral condensate which is the order param eter for spontaneous chiral symmetry breaking in QCD. These formulas provid e the proper way to compute the fermion propagators and may save a signific ant amount of computing time especially for large lattices in four dimensio ns.
