论文摘要
区分拓扑主体零模式和准主要模式 - 琐碎的低能安德里·绑定状态 - 是迈向实现拓扑混合纳米线设备的重要一步。我们建议可以通过将杂种纳米线连接到质量点弱耦合到高电阻铅的量子点实现的耗散谐振水平来做出这种区别。我们表明，谐振水平零偏置电导峰的宽度的定性温度缩放率提供了真正的Majorana零模式独特的签名。进一步证明了由真正的Majorana零模式引起的脱落性，可以稳定该电导峰针对颗粒孔不对称。
Distinguishing between topological Majorana zero modes and quasi Majorana modes -- trivial low energy Andreev bound states -- is an important step towards realizing topological hybrid nanowire devices. We propose that this distinction can be made by connecting a hybrid nanowire to a dissipative resonant level realized by a quantum dot weakly coupled to high resistance leads. We show that the qualitative temperature scaling of the width of the resonant level zero bias conductance peak provides a signature unique to true Majorana zero modes. The degeneracy induced by a true Majorana zero mode is further shown to stabilize this conductance peak against particle-hole asymmetry.
