Modified Lattice Landau Gauge
, 2007
"... 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 3sphere S³ → R³ for SU(2) before imposing the Landau gauge condition. This can reduce the number of Gribov copies exponentially and solves the Gribov pro ..."

Landau Gauge Fixing on GPUs
"... In this paper we present and explore the performance of Landau gauge fixing in GPUs using CUDA. We consider the steepest descent algorithm with Fourier acceleration, and compare the GPU performance with a parallel CPU implementation. Using 324 lattice volumes, we find that the computational power of ..."

The Relationship of the Laplacian Gauge to the Landau Gauge
, 2001
"... The Laplacian gauge for gauge group SU(N) is discussed in perturbation theory. It is shown that 1 to the lowest nontrivial order, 2(g), configurations in the Laplacian gauge automatically satisfy the (finite difference) Landau gauge condition. Laplacian gauge fixed configurations are examined 2 num ..."

Discretisation Errors in Landau Gauge on the Lattice
, 1999
"... Lattice discretisation errors in the Landau gauge condition are examined. An improved gauge fixing algorithm in which O(a 2) errors are removed is presented. It is shown that O(a 2) errors dominate standard gauge fixing procedures and an absolute estimate of the deviation from continuum Landau gauge ..."

Landau gauge Jacobian and BRST symmetry
, 2005
"... We propose a generalisation of the FaddeevPopov trick for YangMills fields in the Landau gauge. The gaugefixing is achieved as a genuine change of variables. In particular the Jacobian that appears is the modulus of the standard FaddeevPopov determinant. We give a path integral representation of ..."

Signatures of confinement in Landau gauge QCD
, 2004
"... Abstract. We summarise an analysis of the infrared regime of Landau gauge QCD by means of a flow equation approach [1]. The infrared behaviour of gluon and ghost propagators is evaluated. The results provide further evidence for the KugoOjima confinement scenario. We also discuss their relation to ..."

COLOR CONFINEMENT IN LATTICE LANDAU GAUGE
, 2003
"... The problem of color confinement in lattice Landau gauge QCD is briefly reviewed in the light of KugoOjima criterion and GribovZwanziger theory. The infrared properties of the Landau gauge QCD is studied by the measurement of the gluon propagator, ghost propagator, KugoOjima parameter and the run ..."

Can the Coulomb and Landau Gauges Be Interpolated?
, 1977
"... We have constructed the Hilbert space of free quantum electrodynamics in a gauge that formally interpolates the Coulomb and Landau gauges: 8 ' A,+ X8 ' Ao =0. The limit as A+0 of the photon propagator in this gauge does not reproduce the propagator in the Coulomb gauge. We infer that the ..."

Landau Gauge within the Gribov Horizon
, 1993
"... We consider a model which effectively restricts the functional integral of Yang–Mills theories to the fundamental modular region. Using algebraic arguments, we prove that this theory has the same divergences as ordinary Yang Mills theory in the Landau gauge and that it is unitary. The restriction of ..."
