L. Deldebbio et al., DETECTION OF CENTER VORTICES IN THE LATTICE YANG-MILLS VACUUM - ART. NO. 094501, Physical review. D. Particles and fields, 5809(9), 1998, pp. 4501
We discuss the implementation of the ''direct'' maximal center gauge (
a gauge which maximizes the lattice average of the squared-modulus of
the trace of link variables), and its use in identifying Z(2) center v
ortices in Yang-Mills vacuum configurations generated by lattice Monte
Carlo calculations. We find that center vortices identified in the va
cuum state account for the full asymptotic string tension. Scaling of
vortex densities with lattice coupling, change in vortex size with coo
ling, and sensitivity to Gribov copies are discussed. Preliminary evid
ence is presented, on small lattices, for center dominance in SU(3) la
ttice gauge theory. [S0556-2821(98)00419-6].
