论文摘要
我们研究了量子转运在石墨烯纳米线中的普遍特性，这些量子纳米线引起了微妙的通用电导波动。我们介绍了三个主要的显微镜模型的结果，这些模型描述了石墨烯的sublattice并如我们将要显示的所有手性通用对称性所示。结果是强大的，即使在许多开放渠道的政权中，也证明了手性的广泛迹象。指纹铺平了用sublattice对称性区分系统（例如拓扑绝缘子）和普通量的指纹。实验实现需要对相关的valleytronics电导的混乱波动进行单一的测量。通过阶段相干长度，我们的理论预测通过文献中有关量子磁通转移的传统测量的数据得到了证实。
We investigate the universal properties of quantum transport in graphene nanowires that engender subtle universal conductance fluctuations. We present results for three of the main microscopic models that describe the sublattice of graphene and generate, as we shall show, all the chiral universal symmetries. The results are robust and demonstrate the widely sought sign of chirality even in the regime of many open channels. The fingerprints paves the way to distinguish systems with sublattice symmetry such as topological insulators from ordinary ones by an order of magnitude. The experimental realization requires a single measurement of the chaotic fluctuations of the associated valleytronics conductante. Through the phase coherence length, our theoretical predictions are confirmed with the data from traditional measurements in the literature concerning quantum magnetotransport.
