Recombination of dyons into calorons in $\mathrm{SU}\left(2\right)\mathrm{}$ lattice fields at low temperatures

By cooling of equilibrium lattice fields at finite temperature in $\mathrm{SU}\left(2\right)\mathrm{}$ gauge theory it has been shown that topological objects (calorons) observed on the lattice in the confined phase possess a dyonic substructure which becomes visible under certain circumstances. Here we show that with the increasing temporal lattice extent the distribution in the caloron parameter space is modified such that the calorons appear nondissociated into constituent dyons. Still the calorons have nontrivial holonomy which is demonstrated by the Polyakov line behavior for these configurations. At vanishing temperature (on a symmetric lattice) topological lumps obtained by cooling show rotational symmetry in 4D for the action density, but a characteristic internal double-peak structure of Polyakov lines with respect to all (temporal and spatial) directions.
