Neutron electric dipole moment with external electric field method in lattice QCD
E. Shintani, S. Aoki, N. Ishizuka +6
We discuss a possibility that the Neutron Electric Dipole Moment (NEDM) can be calculated in lattice QCD simulations in the presence of the CP violating term. In this paper we…
Mobility edge and locality of the overlap-Dirac operator with and without dynamical overlap fermions
JLQCD Collaboration, N. Yamada, S. Aoki +8
We perform a systematic study of low-lying eigenmodes of with various gauge actions to find the optimal choice for dynamical overlap fermion simulations, with which one may a…
Improvement of algorithms for dynamical overlap fermions
JLQCD Collaboration, Hideo Matsufuru, Hidenori Fukaya +7
We investigate the algorithms for dynamical overlap fermions aiming at improving the performance for large-scale simulations. We look for the best combination of Hybrid Monte Carlo…
Dynamical overlap fermions in the epsilon-regime
JLQCD collaboration, H. Fukaya, S. Hashimoto +7
We report on the two-flavor QCD simulation in the epsilon-regime using the overlap fermion formulation. Sea quark mass is reduced to ~ 2 MeV on a 16^3x32 lattice with the lattice s…
Calculation of Neutron EDM in quenched and full QCD
E. Shintani, S. Aoki, N. Ishizuka +5
We report on a direct lattice calculation of the neutron EDM(NEDM) using the external electric field method in both quenched and full QCD. In quenched QCD, we use a …
An estimate of the eta and eta-prime meson masses in Nf=2+1 lattice QCD
CP-PACS, JLQCD Collaborations, : +13
Masses of the eta and eta-prime mesons are estimated in Nf=2+1 lattice QCD with the non-perturbatively O(a) improved Wilson quark action and the Iwasaki RG-improved gluon action, u…
Static quark free energies at finite temperature with two flavors of improved Wilson quarks
Y. Maezawa, S. Ejiri, T. Hatsuda +4
Polyakov loop correlations at finite temperature in two-flavor QCD are studied in lattice simulations with the RG-improved gluon action and the clover-improved Wilson quark action.…
Equation of state for two-flavor QCD with an improved Wilson quark action at non-zero chemical potential
S. Ejiri, T. Hatsuda, N. Ishii +4
The QCD thermodynamics on the lattice provides fundamental theoretical grounds to analyze the various experimental data in relativistic heavy ion collisions. So far, most of the nu…
