论文摘要
我们证明，当嵌入在磁体 - 渗透导体杂种（MSH）系统中时，最近发现的Triple-Q（3Q）磁性结构会引起拓扑超导性的出现。我们研究了域壁上手性majoragan边缘模式的结构，并表明它们可以通过诱导的超恒星的空间分布与微不足道的间隙模式区分开。最后，我们表明，3Q MSH系统中的拓扑超导性是一种强大的现象，不取决于磁性和超导层的相对对准，或者磁性层中具有电子自由度的存在。
We demonstrate that the recently discovered triple-Q (3Q) magnetic structure, when embedded in a magnet-superconductor hybrid (MSH) system, gives rise to the emergence of topological superconductivity. We investigate the structure of chiral Majorana edge modes at domain walls, and show that they can be distinguished from trivial in-gap modes through the spatial distribution of the induced supercurrents. Finally, we show that topological superconductivity in 3Q MSH systems is a robust phenomenon that does not depend on the relative alignment of the magnetic and superconducting layers, or on the presence of electronic degrees of freedom in the magnetic layer.
