30 Sep 2013 | | Abstract: | Topological objects of SU(3) gluodynamics are studied near the transition
temperature with the help of zero and near-zero modes of the overlap Dirac
operator. We construct UV filtered topological charge densities for three
versions of temporal boundary conditions applied to this operator, for which
zero modes are known to be located on corresponding three types of constituent
dyons (antidyons) in the reference case of analytical (anti)caloron solutions.
The clusters of the three topological charge densities mark the positions of
dyons and antidyons which are also present in equilibrium (Monte Carlo) gluonic
fields. We classify them either as constituents of nondissociated
(anti)calorons or as constituents of (anti)dyon pairs or as isolated
(anti)dyons. The pattern of the Polyakov loop is found in these clusters after
a limited number of overimproved cooling steps and resembles predictions from
analytical caloron solutions. | | Source: | arXiv, 1309.7850 | | Services: | Forum | Review | PDF | Favorites | |
