数值研究了无序对二维Z2拓扑绝缘体的影响。本文提出并研究了Bernevig-Hughes-Zhang模型的一个变体的相图，它考虑了sz非守恒自旋轨道耦合。使用标度分析，我们确定的相边界和临界指数表征金属和拓扑绝缘相之间的过渡。
Effects of disorder on a two-dimensional Z2 topological insulator are studied numerically. We propose and study the phase diagram of a variant of Bernevig-Hughes-Zhang model, which takes account of the sz non-conserving spin-orbit coupling. Using scaling analyses, we determine the phase boundary and the critical exponent characterizing the transition between metallic and the topologically insulating phases.
