Abstract

In the second order of the operator form of the perturbation theory, the effective interactions in a superconducting nanowire have been obtained at the strong electron correlations, when the spin–orbit coupling parameter is comparable with the hopping integral. Using the exact diagonalization technique, in short nanowires with the open boundary conditions at the strong Coulomb repulsion, the excitations corresponding to the Majorana edge states with the energy below the value of a bulk superconducting gap have been demonstrated.

自旋-轨道耦合在强相关条件下诱导超导纳米线上的有效相互作用

摘要

在微扰理论的算子形式的第二阶中，当自旋-轨道耦合参数与跳跃积分相当时，在强电子相关性下获得了超导纳米线中的有效相互作用。使用精确的对角化技术，在具有强库仑斥力的开放边界条件的短纳米线中，已经证明了与马里亚纳邦边缘态相对应的激发，其能量低于整体超导间隙的值。
