Evidence of effective axial U(1) symmetry restoration at high temperature QCD
A. Tomiya, G. Cossu, S. Aoki +4
We study the axial U(1) symmetry at finite temperature in two-flavor lattice QCD. Employing the Mobius domain-wall fermions, we generate gauge configurations slightly above the cri…
Stochastic calculation of the Dirac spectrum on the lattice and a determination of chiral condensate in 2+1-flavor QCD
Guido Cossu, Hidenori Fukaya, Shoji Hashimoto +2
We compute the chiral condensate in 2+1-flavor QCD through the spectrum of low-lying eigenmodes of Dirac operator. The number of eigenvalues of the Dirac operator is evaluated usin…
Renormalization of domain-wall bilinear operators with short-distance current correlators
JLQCD collaboration, M. Tomii, G. Cossu +5
We determine the renormalization constants for flavor non-singlet fermion bilinear operators of Möbius domain-wall fermions. The renormalization condition is imposed on the correla…
Anderson Localization in high temperature QCD: background configuration properties and Dirac eigenmodes
Guido Cossu, Shoji Hashimoto
We investigate the properties of the background gauge field configurations that act as disorder for the Anderson localization mechanism in the Dirac spectrum of QCD at high tempera…
Chiral behavior of light meson form factors in 2+1 flavor QCD with exact chiral symmetry
JLQCD Collaboration, T. Kaneko, S. Aoki +6
We present a study of chiral behavior of light meson form factors in QCD with three flavors of overlap quarks. Gauge ensembles are generated at single lattice spacing 0.12 fm with…
Stochastic calculation of the QCD Dirac operator spectrum with Mobius domain-wall fermion
G. Cossu, H. Fukaya, S. Hashimoto +2
We calculate the spectral function of the QCD Dirac operator using the four-dimensional effective operator constructed from the Mobius domain-wall implementation. We utilize the ei…
