AI 中文摘要
我们从理论上研究了在集成邻近诱导超导性与非共线磁体（altermagnetism）的双耦合纳米线中构建拓扑超导电性的可能性。通过调谐可实验获取的参数，我们发现四种不同的拓扑超导相：D类、BDI类，以及每端携带两个马约拉纳零能模的两个相，分别受自旋群和磁点群对称性保护。除继承非共线磁体诱导拓扑超导电性的优势外，该系统还提供超导相位差、线间耦合等多个调谐旋钮以控制拓扑性质。
英文摘要
We theoretically investigate the possibility of engineering topological superconductivity in doubly coupled nanowires integrating proximity-induced superconductivity and altermagnetism. By tuning experimentally accessible parameters, we find four distinct topological superconducting phases: class D, class BDI, and two phases hosting two Majorana zero modes per end, protected respectively by spin-group and magnetic point-group symmetries. Beyond inheriting the advantages of alternating?magnetism induced topological superconductivity, our system provides multiple tuning knobs (e.g., superconducting phase difference and inter-wire coupling) to control topological properties.
