Abstract
With the help of the cooling method applied to SU(2) lattice gauge theory at non-zero T Tc we present numerical evidence for the existence of superpositions of Kraan-van Baal caloron (or BPS monopole pair) solutions with non-trivial holonomy, which might constitute an important contribution to the semi-classical approximation of the partition function.
