Su-Schrieffer-Heeger模型中存在在位无序时手征的持续性
Persistence of chirality in the Su-Schrieffer-Heeger model in the presence of on-site disorder
摘要：
我们考虑了在位无序和跳跃无序对Su-Schrieffer-Heeger模型中零模的影响。在没有无序畴壁引起两个手性分馏束缚态，一个在边缘和一个绑定到畴壁。与跳跃无序相反，原位无序破坏了手征对称性。利用极化的方法，我们发现，在弱到中等无序的束缚态的手征性质的影响很小，在现场的无序。我们探讨这些束缚态的行为，强烈的障碍，对比现场和跳跃的障碍，并连接我们的结果的本地化属性的束缚态和最近的实验。
英文摘要：
We consider the effects of on-site and hopping disorder on zero modes in the Su-Schrieffer-Heeger model. In the absence of disorder a domain wall gives rise to two chiral fractionalized bound states, one at the edge and one bound to the domain wall. On-site disorder breaks the chiral symmetry, in contrast to hopping disorder. By using the polarization we find that on-site disorder has little effect on the chiral nature of the bound states for weak to moderate disorder. We explore the behaviour of these bound states for strong disorder, contrasting on-site and hopping disorder and connect our results to the localization properties of the bound states and to recent experiments.
