M. Feurstein et al., TOPOLOGY WITHOUT COOLING - INSTANTONS AND MONOPOLES NEAR TO DECONFINEMENT, Nuclear physics. B, Proceedings supplement, 63, 1998, pp. 480-485
In an attempt to describe the change of topological structure of pure
SU(2) gauge theory near deconfinement a renormalization group inspired
method is tested. Instead of cooling, blocking and subsequent inverse
blocking is applied to Monte Carlo configurations to capture topologi
cal features at a well-defined scale. We check that this procedure lar
gely conserves long range physics like string tension. UV fluctuations
and lattice artefacts are removed which otherwise spoil topological c
harge density and Abelian monopole currents. We report the behaviour o
f topological susceptibility and monopole current densities across the
deconfinement transition and relate the two faces of topology to each
other. First results of a cluster analysis are described.
