我们揭示了一种实现层锁定拓扑相的通用机制。基于该机制,我们研究了在具有s波配对的非对称双层反铁磁系统中实现层锁定手性拓扑超导性(即量子反常层霍尔效应的超导类似物)。我们确定了三种不同的栅极可调拓扑相,并建立了近量子化层分解陈数与手性马约拉纳边缘态、涡旋核马约拉纳零模以及近量子化热霍尔响应的层锁定行为之间的直接对应关系。
英文摘要
We uncover a universal mechanism for realizing layer-locked topological phases. Guided by it, we investigate the realization of layer-locked chiral topological superconductivity-the superconducting analogue of the quantum anomalous layer Hall effect-in a nonsymmorphic bilayer antiferromagnetic system with s-wave pairing. We identify three distinct gate-tunable topological phases and establish a direct correspondence between the nearly quantized layer-resolved Chern numbers and the layer-locking behavior of chiral Majorana edge states, vortex-core Majorana zero modes, and nearly quantized thermal Hall responses.
