Query: Center vortices in MCG - finite-size and gauge-copy effects   In SU(2) lattice gauge theory in maximal center gauge, we investigate the
dependence of center-projected Creutz ratios and the vortex density on lattice
size and the number of gauge copies. The dependence on the number of copies is
rather strong on small lattices, but almost disappears on lattices sufficiently
large compared to the expected average vortex thickness. The center-projected
string tension, evaluated on sufficiently large lattices, is in good agreement
with the full asymptotic string tension, and the vortex density scales
according to the second-order asymptotic-freedom formula.
