论文摘要
为了确认Majorana签名，已大力致力于区分Majorana零模式（MZM）和空间分离的准毛毛菌模式（QMMS）。由于MZM和QMM在电导测量中引起量化的零偏置峰，因此认为它们的验证任务非常困难。在这里，我们提出了一个带有单个纳米线的简单设备，该设备可以在拓扑范围内具有四个QMM的拓扑临床效应的明确证据。另一方面，在具有MZM的拓扑超导阶段，传输特征显着差异。因此，我们的计划提供了一种区分Majoraana和Quasi-Majorana模式的简单方法。
To confirm the Majorana signatures, significant effort has been devoted to distinguishing between Majorana zero modes (MZMs) and spatially separated quasi-Majorana modes (QMMs). Because both MZMs and QMMs cause a quantized zero-bias peak in the conductance measurement, their verification task is thought to be very difficult. Here, we proposed a simple device with a single nanowire, where the device could develop clear evidence of the topological Kondo effect in the topologically trivial phase with four QMMs. On the other hand, in the topological superconducting phase with MZMs, the transport signatures are significantly different. Therefore, our scheme provides a simple way to distinguish Majorana and quasi-Majorana modes.
