Title:
Classical Interactions and numerical studies of the instanton-dyon ensemble
Speaker:
Abstract:
Instanton-dyons, also known as instanton-monopoles or instanton-quarks, are topological constituents of the instantons at nonzero temperature and holonomy. Classical interactions of the dyons have been found and included in numerical simulations of the ensemble of interacting dyons for SU(2) pure gauge theory. The focus of the talk is the back reaction on the holonomy and the issue of confinement, but I will also devote time to explain the structure of the dyons and their classical interactions. The free energy has been calculated as a function of the holonomy and the dyon densities, using standard Metropolis Monte Carlo and integration over parameter methods. It is observed that as the temperature decreases and the dyon density grows, the minimum of the free energy indeed moves from small holonomy to the value corresponding to confinement
