本文报道了二维自旋轨道耦合系统中安德森跃迁的数值研究。据我们所知，文献中还没有报道过在这个普适性类的本地化长度的发散的临界指数nu的准确估计。在这里我们分析SU（2）模型。我们发现，对于这个模型，由于不相关的缩放变量的缩放校正可以忽略不计，允许准确估计的指数nu=2.73+/-0.02。
We report a numerical investigation of the Anderson transition in two-dimensional systems with spin-orbit coupling. An accurate estimate of the critical exponent nu for the divergence of the localization length in this universality class has to our knowledge not been reported in the literature. Here we analyze the SU(2) model. We find that for this model corrections to scaling due to irrelevant scaling variables may be neglected permitting an accurate estimate of the exponent nu=2.73+/-0.02.
