Using supersymmetry, we map a model for this transition onto the two-dimensional percolation problem. The anisotropic limit is an sl(2|1) supersymmetric spin chain. The mapping gives exact values for critical exponents associated with disorder-averages of several observables in good agreement with recent numerical results.5 pages, 2 figuresMesoscale and Nanoscale PhysicsDisordered Systems and Neural NetworksSuperconductivityHigh Energy Physics - Theorytext
