Gribov copies and gauge fixing in lattice gauge theories
Description
We address the problem of the gauge fixing versus Gribov copies in lattice gauge theories. For the Landau gauge, results show that a suitable combination of evolutionary algorithms with traditional steepest descent methods identifies the global maximum of the optimisation function. We discuss the performance of the combined algorithm on small cubic lattices for SU(2) and SU(3). http://www.sciencedirect.com/science/article/B6TVD-45XSH59-BS/1/8511f25b41a9ee57cf94c004ad736218
