New algorithm for gauge fixing in SU(2) lattice gauge theory

Abstract

An overrelaxed variant of simulated annealing is applied to the problem of maximally abelian gauge fixing. The superiority of this algorithm over the commonly used relaxation procedure is demonstrated. Biases on non gauge invariant quantities due to gauge fixing ambiguities are discussed.Comment: Talk given at the LATTICE '94 International Symposium on Lattice Field Theory, Bielefeld, Germany, September 27 -- October 1, 1994. 4 pages, uuencode
