Parallel tempering and decorrelation of topological charge in full QCD
E. -M. Ilgenfritz, W. Kerler, M. Müller-Preussker +1
The improvement of simulations of QCD with dynamical Wilson fermions by combining the Hybrid Monte Carlo algorithm with parallel tempering is studied on and lattices.…

Lorentz gauge fixing and lattice QED
I. L. Bogolubsky, V. K. Mitrjushkin, M. Muller-Preussker +2
The Gribov ambiguity problem is studied for compact lattice QED within the Lorentz gauge. In the Coulomb phase, Gribov copies are mainly caused by double Dirac sheets and zero-mome…

Half-integer topological charges below and above the deconfinement transition?
E. -M. Ilgenfritz, M. Muller-Preussker, A. I. Veselov
For pure SU(2) lattice gauge theory at finite T, by the help of the cooling method, we search for classical (approximate) solutions having non-trivial holonomy at the spatial bound…
