Relativistic corrections to the static potential at O(1/m) and O(1/m^2)
Yoshiaki Koma, Miho Koma, Hartmut Wittig
We investigate the relativistic corrections to the static potential, i.e. the O(1/m) potential and the O(1/m^2) velocity-dependent potentials, in SU(3) lattice gauge theory. They a…
The chiral transition on a 24^3x10 lattice with N_f=2 clover sea quarks studied by overlap valence quarks
V. Weinberg, E. -M. Ilgenfritz, K. Koller +4
Overlap fermions are particularly well suited to study the finite temperature dynamics of the chiral symmetry restoration transition of QCD, which might be just an analytic crossov…
Localization of overlap modes and topological charge, vortices and monopoles in SU(3) LGT
E. -M. Ilgenfritz, K. Koller, Y. Koma +4
We present selected recent results of the QCDSF collaboration on the localization and dimensionality of low overlap eigenmodes and of the topological density in the quenched SU(3)…
Gauge-independent Abelian mechanism of color confinement in gluodynamics
Tsuneo Suzuki, Katsuya Ishiguro, Yoshiaki Koma +1
Abelian mechanism of non-Abelian color confinement is observed in a gauge-independent way by high precision lattice Monte Carlo simulations in gluodynamics. An Abelian gauge field…
Exploring the structure of the quenched QCD vacuum with overlap fermions
E. -M. Ilgenfritz, K. Koller, Y. Koma +3
Overlap fermions have an exact chiral symmetry on the lattice and are thus an appropriate tool for investigating the chiral and topological structure of the QCD vacuum. We study va…
Abelian dominance and the dual Meissner effect in local unitary gauges in SU(2) gluodynamics
Toru Sekido, Katsuya Ishiguro, Yoshiaki Koma +2
Performing highly precise Monte-Carlo simulations of SU(2) gluodynamics, we observe for the first time Abelian dominance in the confining part of the static potential in local unit…
