Keywords: | Lattice QCD; Landau gauge; Gauge fixing; Gribov copies | Issue Date: | 2004 | Citation: | Computer Physics Communications. 158:2 (2004) 73-88 | Abstract: | An algorithm for gauge fixing to the Landau gauge in the fundamental modular region in lattice QCD is described. The method, a combination of an evolutionary algorithm with a steepest descent method, is able to solve the problem of the nonperturbative gauge fixing. The performance of the combined algorithm is investigated on 84, [beta]=5.7, and 164, [beta]=6.0, lattice SU(3) gauge configurations. | URI: | https://hdl.handle.net/10316/4451 | DOI: | 10.1016/j.cpc.2003.12.001 | Rights: | openAccess |
