We study a model of dyons for SU(2) Yang-Mills theory, in particular its ability to generate a confining force between a static quark antiquark pair.
The interaction between dyons corresponds to a long range potential, which in a naive treatment with a finite number of dyons gives rise to severe finite volume effects.
To avoid such effects we apply the so-called Ewald method, which has its origin in plasma physics.
The basic idea of Ewald's method is to consider a finite number of dyons inside a finite cubic volume and enforce periodicity of this volume.
In this talk we apply Ewalds method to the logarithmic dyon potential, which is then used to simulate an ensemble of dyons by means of Monte Carlo methods.
We also present preliminary results regarding the static quark antiquark potential within this model.
