Orbital magnetoelectric coupling of three dimensional Chern insulators
Abstract Orbital magnetoelectric effect is closely related to the band topology of bulk crystalline insulators. While the half quantized Chern-Simons coupling is well defined only for insulators with zero Chern number, such as three dimensional (3D) axion insulators, the orbital magnetoelectric effe...
