摘要:We review briefly recent results of lattice simulations on 3d domains in the vacuum state of
SU(2) gluodynamics. The defects are defined as unification of all the negative links in central
projection under condition that the total number of negative links is minimized. In the continuum
limit, negative links correspond, generally speaking to singular fields. The data indicate that total
volume of the defects scales in physical units. We consider also correlator of negative links. The
correlator scales in physical units as well, within the error bars. A new observation reported here
is a strong anisotropy of the correlator.
