Lattice gradient flows (de-)stabilizing topological sectors

Abstract We investigate the stability of topological charge under gradient flow taking the admissibility condition into account. For the SU(2) Wilson gauge theory with β = 2.45 and L 4 = 124, we numerically show that the gradient flows with the Iwasaki and DBW2 gauge actions stabilize the topologica...
