Confinement in Polyakov Gauge — •Florian Marhauser and Jan Martin Pawlowski — Institut für Theoretische Physik, Universität Heidelberg, Philosophenweg 16, D-69120 Heidelberg

The Polyakov loop is the order parameter for confinement. We compute its effective action and thereby the critical temperature using functional renormalization group methods. For SU(2) Yang-Mills theory we observe a second order phase transition and a critical temperature compatible with lattice gauge theory results. Extensions of the calculation are discussed.
