Interacting dyon ensemble and confinement by particle mesh Ewald's method

TL;DR

This paper investigates how interactions among dyons influence quark confinement, showing that interactions increase string tension and lower the confinement temperature in a static quark-antiquark pair.

Contribution

It introduces a method to compute the free energy of a quark-antiquark pair in an interacting dyon ensemble near deconfinement using particle mesh Ewald's method.

Findings

Interacting dyons increase the string tension.

Confinement temperature decreases with interactions.

Comparison with noninteracting case highlights the impact of interactions.

Abstract

The free energy of a static quark-antiquark pair is obtained in an interacting dyon ensemble near the deconfinement temperature. Comparing the results with the noninteracting case, we observe that the string tension between the quark-antiquark pair increases for the interacting ensemble. As a result, the confinement temperature decreases.
