Orbital Magnetization of Interacting Electrons
Xi Chen, Zhi-Da Song
We derive an exact expression for the orbital magnetization of electrons with short-range interactions (such as density-density interactions) in terms of exact zero-frequency respo…

Intrinsic (Axion) Statistical Topological Insulator
Xi Chen, Fa-Jie Wang, Zhen Bi +1
Ensembles that respect symmetries on average exhibit richer topological states than those in pure states with exact symmetries, leading to the concept of average symmetry-protected…
