Quark condensate in two-flavor QCD
Thomas DeGrand, Zhaofeng Liu, Stefan Schaefer
Abstract
We compute the condensate in QCD with two flavors of dynamical fermions using numerical simulation. The simulations use overlap fermions, and the condensate is extracted by fitting the distribution of low lying eigenvalues of the Dirac operator in sectors of fixed topological charge to the predictions of Random Matrix Theory.
