,我们提出了一个理论框架,用于在存在二维(2D)磁性阵列的磁性阵列的情况下,在不受规定的超导电器的顶部产生二维(2D)磁性磁盘阵列,以产生无间隙拓扑超导性(GTSC)托管Majoraana Flat Edge模式(MFEM)。Our observations reveal two distinct topological phase transitions within the emergent Shiba band depending on the exchange coupling strength ( J ) between magnetic adatom spins and superconducting electrons: the first one designates transition from gapless non-topological to gapless topological phase at lower J , while the second one denotes transition from gapless topological to a trivial gapped superconducting phase at higher J .无间隙拓扑超导阶段在J的中间值(托管MFEM)的中间值中存活。此外,我们研究了批量有效配对的性质,这些配对表明GTSC出现是由于伪“ s -Wave”和伪“ P x + p y”类型的配对的相互作用。因此,我们的研究为基于D波超导体作为高温平台的2D Shiba晶格实现GTSC的实验开辟了一个有希望的途径。
