本文报道了一个具有自旋轨道耦合的二维非相互作用电子系统中安德森局域化的数值研究。我们分析了二维SU(2)模型的重整化局域化长度的尺度，并在从局域化极限到金属极限的整个范围内估计了它的$\beta$-函数。
We report a numerical study of Anderson localization in a 2D system of non-interacting 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.
