摘要：
We present a combination of analytical and numerical calculations for the critical behavior of a supersymmetric nonlinear sigma model. This toy model is expected to describe at least qualitatively the localization transition of a disordered one-electron system. As a result, we obtain a localization length exponent and a set of inverse participation numbers in three dimensions. We find a continuous phase transition with the features of one-parameter scaling and multifractality at the critical point.
