论文摘要
与超导体耦合的一维系统可以通过外部磁场将其驱动到拓扑超导阶段。在这里，我们研究了磁场在II型超导体中产生的涡度的效果，从而提供了接近效应。我们确定了对主要模式的拓扑保护的不同方式，并讨论了规避这些有害影响的策略。我们的发现也与接近量子大厅边缘状态的拓扑阶段有关。
One-dimensional systems proximity-coupled to a superconductor can be driven into a topological superconducting phase by an external magnetic field. Here, we investigate the effect of vortices created by the magnetic field in a type-II superconductor providing the proximity effect. We identify different ways in which the topological protection of Majorana modes can be compromised and discuss strategies to circumvent these detrimental effects. Our findings are also relevant to topological phases of proximitized quantum Hall edge states.
