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…
Effects of near-zero Dirac eigenmodes on axial U(1) symmetry at finite temperature
Akio Tomiya, Guido Cossu, Hidenori Fukaya +2
We study the axial U(1)A symmetry of Nf = 2 QCD at finite temperature using the Dirac eigenvalue spectrum. The gauge configurations are generated employing the Mobius domain-wall f…
Scaling study of an improved fermion action on quenched lattices
Yong-Gwi Cho, Shoji Hashimoto, Jun-Ichi Noaki +4
We present scaling studies for heavy-quark observables calculated with an -improved fermion action on tree-level Symanzik improved gauge configurations. Lattices of $1/a =…
Axial U(1) symmetry at finite temperature with Möbius domain-wall fermions
JLQCD Collaboration, Guido Cossu, Hidenori Fukaya +4
We investigate the axial symmetry restoration at finite temperature in two flavor QCD. We employ the Möbius domain-wall formalism that is designed to achieve good chiral sym…
