Indeed, supersymmetry relates correlation functions in a D-dimensional disordered system with some other correlation functions in a D - 2 clean system. We first show how to check these relationships in a finite-size scaling calculation and then perform a high-accuracy test. While the supersymmetric predictions are satisfied even to our high accuracy at D = 5, they fail to describe our results at D = 4.engjournal articlehttp://dx.doi.org/10.1103/PhysRevLett.122.240603https://journals.aps.org/open access53Lower Critical DimensionRandom Magnetic-FieldsCritical-BehaviorBranched PolymersPhase-TransitionsReductionExponents.Física (Física)22 Física
