M. Feurstein et al., CORRELATION-FUNCTIONS BETWEEN TOPOLOGICAL OBJECTS - FIELD THEORETIC VERSUS GEOMETRIC DEFINITIONS, Nuclear physics. B, 1997, pp. 550-552
We analyze topological objects in pure gluonic SU(2) lattice gauge the
ory and compute correlation functions between instantons and monopoles
. Concerning the instantons we use geometric and field theoretic defin
itions of the topological charge. On a 12(3) x 4 lattice it turns out
that topological quantities have a non-trivial-local correlation. The
auto-correlation functions of the topological charge depend on cooling
for both definitions. We fit the correlation functions to exponential
s and obtain screening masses.
