Topological Vortex Phase Transitions in Iron-Based Superconductors

10 Jan 2019 Qin Shengshan Hu Lunhui Wu Xianxin Dai Xia Fang Chen Zhang Fu-chun Hu Jiangping

We study topological vortex phases in iron-based superconductors. Besides the previously known vortex end Majorana zero modes (MZMs) phase stemming from the existence of a three dimensional (3D) strong topological insulator state, we show that there is another topologically nontrivial phase as iron-based superconductors can be doped superconducting 3D weak topological insulators (WTIs)...
