Making Chiral Topological Superconductivities from Non-topological Superconductivities Through the Twist
Yu-Bo Liu, Jing Zhou, Yongyou Zhang +2
In this paper, we propose a general scheme to realize chiral TSCs through the "twistronics". Suppose we have a -symmetric monolayer superconductor, which carries non-topologic…
