Determination of chiral condensate from low-lying eigenmodes of Mobius domain-wall Dirac operator
G. Cossu, H. Fukaya, S. Hashimoto, T. Kaneko, J.I. Noaki
We calculate the spectral function of the Mobius domain-wall Dirac operator utilizing a stochastic eigenvalue counting technique. From the low-end of the spectrum we extract the chiral condensate in 2+1-flavor QCD, and take the chiral and continuum limits. Lattice ensembles are those generated with Mobius domain-wall fermions at a ~ 0.080, 0.055 and 0.044 fm.
