论文摘要
范德华异质结构中拓扑超导状态的出现为探索控制拓扑超导体的新型策略提供了一个新的平台。尤其是，范德华异质结构中的杂质通常以Moire模式为特征，可能会导致原子和Moire长度尺度之间的独特相互作用，这是通用拓扑超导体中不存在的特征。在这里，我们考虑了非磁性杂质对弱和强大政权的拓扑Moire超导体的影响，考虑到原始原始的无限Moire系统中的周期性阵列和单个杂质。我们证明了杂质诱导的模式与摩尔长度之间的良好相互作用，这取决于相对杂质的位置和摩尔长度，从而导致截然不同的光谱和拓扑特性。我们的结果突出了杂质在具有Moire模式的范德华异质结构中的关键作用，从而揭示了人工Moire系统中的长度和能量尺度之间的关键相互作用。
The emergence of a topological superconducting state in van der Waals heterostructures provides a new platform for exploring novel strategies to control topological superconductors. In particular, impurities in van der Waals heterostructures, generically featuring a moire pattern, can potentially lead to the unique interplay between atomic and moire length scales, a feature absent in generic topological superconductors. Here we address the impact of non-magnetic impurities on a topological moire superconductor, both in the weak and strong regime, considering both periodic arrays and single impurities in otherwise pristine infinite moire systems. We demonstrate a fine interplay between impurity-induced modes and the moire length, leading to radically different spectral and topological properties depending on the relative impurity location and moire lengths. Our results highlight the key role of impurities in van der Waals heterostructures featuring moire patterns, revealing the key interplay between length and energy scales in artificial moire systems.
