As an approach to describe the long-range properties of non-Abelian gauge theories at nonzero temperature T < T-c, we consider a noninteracting ensemble of dyons (magnetic monopoles) with nontrivial holonomy. We show analytically that the quark-antiquark free energy from the Polyakov loop correlator grows linearly with the distance, and how the string tension scales with the dyon density. In numerical treatments, the long-range tails of the dyon fields cause severe finite-volume effects. Therefore, we demonstrate the application of Ewald's summation method to this system. Finite-volume effects are shown to be under control, which is a crucial requirement for numerical studies of interacting dyon ensembles.
