The strong-coupling limit of lattice Landau gauge
Andre Sternbeck, Lorenz von Smekal
We report on our recent study of the gluon and ghost propagators of pure SU(2) minimal lattice Landau gauge in the strong-coupling limit. In this limit, we find evidence of the con…
Lattice Landau gauge via Stereographic Projection
Lorenz von Smekal, Alexander Jorkowski, Dhagash Mehta +1
The complete cancellation of Gribov copies and the Neuberger 0/0 problem of lattice BRST can be avoided in modified lattice Landau gauge. In compact U(1), where the problem is a la…
Landau Gauge QCD: Functional Methods versus Lattice Simulations
Lorenz von Smekal
The infrared behaviour of QCD Green's functions in Landau gauge has been focus of intense study. Different non-perturbative approaches lead to a prediction in line with the conditi…
Decontracted double BRST on the lattice
Lorenz von Smekal, Marco Ghiotti, Anthony G Williams
We present the Curci-Ferrari model on the lattice. In the massless case the topological interpretation of this model with its double BRST symmetry relates to the Neuberger 0/0 prob…
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…
