摘要：

We report a numerical study of Anderson localization in a two-dimensional (2D) system of noninteracting electrons with spin-orbit coupling. We analyze the scaling of the renormalized localization length for the 2D SU(2) model and estimate its beta function over the full range from the localized to the metallic limits.
