Abstract: We show numerically that the lowest eigenmodes of the two-dimensional Laplace operator with SU(2) gauge couplings and periodic boundary conditions are strongly localized. A connection is drawn to the Anderson localization problem. A new multigrid algorithm, capable of dealing with these modes, shows no critical slowing down for this problem independent of the disorder.
