The Landau gauge gluon propagator: Gribov problem and finite-size effects
I. L. Bogolubsky, V. G. Bornyakov, G. Burgio +4
The SU(2) gluon propagator in Landau gauge is studied on the lattice. Our gauge fixing procedure employs simulated annealing and Z(2)-flips. It finds higher maxima of the gauge fun…
Coulomb gauge Green functions and Gribov copies in SU(2) lattice gauge theory
M. Quandt, G. Burgio, S. Chimchinda +1
We reconsider the lattice measurement of Green functions in Coulomb gauge, both in 2+1 and 3+1 dimensions, using an improved gauge fixing scheme. The influence of Gribov copies is…
Vortex topology and the continuum limit of lattice gauge theories
G. Burgio
We study the stability of Z_2 topological vortex excitations in d+1 dimensional SU(2) Yang-Mills theory on the lattice at T=0. This is found to depend on d and on the coupling cons…
Hamiltonian approach to Coulomb gauge Yang-Mills Theory
H. Reinhardt, W. Schleifenbaum, D. Epple +1
The vacuum wave functional of Coulomb gauge Yang-Mills theory is determined within the variational principle and used to calculate various Green functions and observables. The resu…
Improved Landau gauge fixing and the suppression of finite-volume effects of the lattice gluon propagator
I. L. Bogolubsky, V. G. Bornyakov, G. Burgio +3
For the gluon propagator of pure SU(2) lattice gauge theory in the Landau gauge we investigate the effect of Gribov copies and finite-volume effects. Concerning gauge fixing, we en…
