Eigenvalue repulsion in an effective theory of SU(2) Wilson lines in three dimensions — Adrian Dumitru and •Dominik Smith — Institut für Theoretische Physik, Universität Frankfurt

We perform simulations of an effective theory of SU(2) Wilson lines in three dimensions. We include a non-perturbative ``fuzzy-bag'' contribution which is added to the one-loop perturbative potential for the Wilson line. We confirm that, at moderately weak coupling, this leads to eigenvalue repulsion in a finite region above the deconfining phase transition which shrinks in the extreme weak-coupling limit. A non-trivial Z(N) symmetric vacuum arises in the confined phase.
