Lattice simulation of a center symmetric three-dimensional effective theory for SU(2) Yang-Mills — •Dominik Smith1, Stefan Schramm1, and Adrian Dumitru2 — 1Universität Frankfurt, ITP, Max-von-Laue Str.1, 60438 Frankfurt — 2Baruch College, Dept. of Natural Sciences, 17 Lexington Ave., New York, NY 10010, USA
We perform simulations of an effective theory of SU(2) Wilson lines in three dimensions. Our action includes a kinetic term, the one-loop perturbative potential for the Wilson line, a non-perturbative "fuzzy-bag" contribution and spatial gauge fields. We determine the phase diagram of the theory and confirm that, at moderately weak coupling, the non-perturbative term leads to eigenvalue repulsion in a finite region above the deconfining phase transition.
