摘要:
我们研究了具有电子动量三次方的Rashba型自旋轨道耦合的二维模型的性质。在正常相中,开边界上会出现边缘态。在超导相中,边缘态可能演化为有能隙的费米子边缘态。还讨论了其在界面超导体实际材料中的应用。
英文摘要:
We investigate the properties of the two-dimensional model with Rashba-type spin-orbit coupling cubic in electron momentum. In the normal phase, edge states emerge on open boundaries. In the superconducting phase, edge states could evolve into gapped fermionic edge states. Applications to realistic materials of interface superconductors are also discussed.
