论文摘要
弱层间范德华材料\ {beta} -bi2pd最近被确定为具有非常规的自旋三个旋转三层配对和Majorana零模式的强拓扑超导体候选者。在这封信中,我们研究了单层\ {beta} -BI2PD在单层中仍然晦涩难懂的拓扑特征和超导配对,鉴于我们有效的理论模型。我们发现,非拉什巴旋转轨道耦合在实现和调整各种新颖的拓扑表现方面起着至关重要的作用。特别是,单层\ {beta} -bi2pd揭示了与Majorana零模式的自旋 - 三杆P波超导配对。我们的研究加深了对单层\ {beta} -BI2PD中拓扑和超导性的理解,并表明它是实现低代数拓扑超导性的有前途的平台。
The weak interlayer Van Der Waals material \{beta}-Bi2Pd has recently been established as a strong topological superconductor candidate with unconventional spin-triplet pairing and Majorana zero modes at vortices. In this letter, we study the topological characters and the superconducting pairing, which are still obscure in monolayer \{beta}-Bi2Pd, in light of our effective theoretical model. We find that the non-Rashba spin-orbital coupling plays a critical role in realizing and tuning various novel topological natures. In particular, the spin-triplet p-wave superconducting pairing with Majorana zero mode is revealed in monolayer \{beta}-Bi2Pd. Our studies deepen the understanding of topology and superconductivity in monolayer \{beta}-Bi2Pd and indicate it is a promising platform for achieving low-dimentional topological superconductivity.
