Twisted magnetic topological insulators
Chao-Kai Li, Xu-Ping Yao, Gang Chen
Motivated by the discovery of the quantum anomalous Hall effect in Cr-doped \ce{(Bi,Sb)2Te3} thin films, we study the generic states for magnetic topological insulators and explore…

Writing and deleting skyrmions with electric fields in a multiferroic heterostructure
Chao-Kai Li, Xu-Ping Yao, Gang Chen
Magnetic skyrmions are topological spin textures that can be used as information carriers for the next-generation information storage and processing. The electric-field controlling…
