论文摘要
我们提出了一个新的实现，该实现是根据量子自旋霍尔系统托管Majoraana零模型的拓扑超导相。值得注意的是，我们的建议完全没有铁磁铁。取而代之的是，我们将螺旋边缘限制在二维拓扑绝缘体中有限长度的狭窄缺陷线周围。我们证明了新的拓扑结构的形成，在存在S波超导性和Zeeman耦合的情况下托管受保护的主要模式。有趣的是，当该系统与螺旋边缘状态储层较弱时，特定的传输签名与非亚伯利亚主要零模式的存在有关。
We propose a novel realization for a topologically superconducting phase hosting Majorana zero-modes on the basis of quantum spin Hall systems. Remarkably, our proposal is completely free of ferromagnets. Instead, we confine helical edge states around a narrow defect line of finite length in a two-dimensional topological insulator. We demonstrate the formation of a new topological regime, hosting protected Majorana modes in the presence of s-wave superconductivity and Zeeman coupling. Interestingly, when the system is weakly tunnel-coupled to helical edge state reservoirs, a particular transport signature is associated with the presence of a non-Abelian Majorana zero-mode.
