Abstract

We report results of a numerical study of noninteracting electrons moving in two dimensions, in the presence of a random potential and a random magnetic field for a sequence of finite sizes, using topological properties of the wave functions to identify extended states. Our results are consistent with the existence of a second order localization-delocalization transition driven by the random potential. The critical randomness strength and localization length exponent are estimated via a finite-size scaling analysis.
