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…
Gauge invariant properties of Abelian monopoles
S. Thurner, H. Markum, E. -M. Ilgenfritz +1
Using a renormalization group motivated smoothing technique, we investigate the large scale structure of lattice configurations at finite temperature, concentrating on Abelian mono…
Modified lattice gauge theory: towards realistic lattice QED
V. G. Bornyakov, V. K. Mitrjushkin, M. Müller-Preussker
We study properties of the compact lattice gauge theory with monopoles {\it removed}. Employing Monte Carlo simulations we calculate correlators of scalar, vector and…
