Center vortices and the quark propagator in SU(2) gauge theory
Patrick O. Bowman, Kurt Langfeld, Derek B. Leinweber +4
We study the behavior of the AsqTad quark propagator in Landau gauge on quenched SU(2) gauge configurations under the removal of center vortices. In contrast to recent results in S…
The effective Coulomb potential in SU(3) lattice Yang-Mills theory
A. Voigt, E. -M. Ilgenfritz, M. Müller-Preussker +1
We study the infrared behavior of the effective Coulomb potential in lattice SU(3) Yang-Mills theory in the Coulomb gauge. We use lattices up to a size of 48^4 and three values of…
The gluon propagator from large asymmetric lattices
O. Oliveira, P. J. Silva, E. -M. Ilgenfritz +1
The Landau-gauge gluon propagator is computed for the SU(3) gauge theory on lattices up to a size of . We use the standard Wilson action at and compare ou…
Coulomb gauge studies of SU(3) Yang-Mills theory on the lattice
Aiko Voigt, Ernst-Michael Ilgenfritz, Michael Mueller-Preussker +1
We study the infrared behaviour of lattice SU(3) Yang-Mills theory in Coulomb gauge in terms of the ghost propagator, the Coulomb potential and the transversal and the time-time co…
Scaling behavior and positivity violation of the gluon propagator in full QCD
Patrick O. Bowman, Urs M. Heller, Derek B. Leinweber +5
The Landau-gauge gluon propagator is studied using the coarse and fine dynamical MILC configurations. The effects of dynamical quarks are clearly visible and lead to a reduction of…
A numerical reinvestigation of the Aoki phase with N_f=2 Wilson fermions at zero temperature
E. -M. Ilgenfritz, W. Kerler, M. Mueller-Preussker +2
We report on a numerical reinvestigation of the Aoki phase in lattice QCD with two flavors of Wilson fermions where the parity-flavor symmetry is spontaneously broken. For this pur…
