论文摘要
从理论上讲，我们研究轨道依赖性交换场在二阶拓扑超导体形成中的影响。我们证明，改变轨道差可以诱导拓扑转换，并且可以操纵其中的Majorana角模式。我们进一步建议通过正常探针终端检测角模式。发现电导量化对相关系统参数的变化是可靠的。
We theoretically study the effect of orbital-dependent exchange field in the formation of second order topological superconductors. We demonstrate that changing the orbital difference can induce topological transition and the Majorana corner modes therein can be manipulated. We further propose to detect the corner modes via a normal probe terminal. The conductance quantization is found to be robust to changes of the relevant system parameters.
