We propose a modified lattice Landau gauge based on stereographically projecting the link variables on the circle S^1 -> R for compact U(1) or the 3-sphere S^3 -> R^3 for SU(2) before imposing the Landau gauge condition. This can reduce the number of Gribov copies exponentially and solves the Gribov problem in compact U(1) where it is a lattice artifact. Applied to the maximal Abelian subgroup this might be just enough to avoid the perfect cancellation amongst the Gribov copies in a lattice… Expand

When fixing a covariant gauge, most popularly the Landau gauge, on the lattice one encounters the Neuberger 0/0 problem which prevents one from formulating a Becchi--Rouet--Stora--Tyutin symmetry onExpand

A lattice gauge theory framework for simulations on graphic processing units (GPUs) using NVIDIA’s CUDA is presented and a mixed-precision scheme that performs the critical parts of the algorithm in full DP while retaining 80%–90% of the SP performance is suggested. Expand
On gauge fixing
Gauge fixing is a useful tool to simplify calculations. It is also valuable to combine different methods, in particular lattice and continuum methods. However, beyond perturbation theory theExpand

• 2010
Gauge fixing in the non-perturbative domain of non-Abelian gauge theories is obstructed by the Gribov–Singer ambiguity, so the various results available for correlation functions could possibly correspond to different non- perturbative Landau gauges, discriminated by an additional non-erturbative gauge parameter.
