Lattice simulation of a center symmetric three-dimensional effective theory for SU(2) Yang-Mills — •Dominik Smith1, Stefan Schramm1, and Adrian Dumitru2 — 1Universität Frankfurt, Institut für theoretische Physik, Germany — 2Baruch College, Dept. of Natural Sciences, New York, 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.
