论文摘要
我们表明,Zeeman场可以在二维自旋轨道耦合金属中诱导拓扑过渡,并同时在超导状态中的一阶相变,涉及库珀配对动量的不连续变化。根据自旋轨道耦合强度,我们在面内磁场下发现2D超导体的不同相图。
We show that Zeeman field can induce a topological transition in two-dimensional spin-orbit coupled metals, and concomitantly, a first-order phase transition in the superconducting state involving a discontinuous change of Cooper pair momentum. Depending on the spin-orbit coupling strength, we find different phase diagrams of 2D superconductors under in-plane magnetic field.
