Field Response of the Orbital Moment Probed by Integrated Magnetic Circular Dichroism
Qian-Sheng Shi, Ziqiang Wang, Jian Kang +1
Magnetic circular dichroism (MCD) is an optical probe of orbital time reversal symmetry breaking. Although frequency integrated MCD is related to the self-rotation contribution to…

Contribution of remote bands to orbital magnetization in twisted bilayer graphene
Pinzhuo Li, Kun Jiang, Ziqiang Wang +2
Motivated by recent theoretical and experimental works on orbital magnetization for the interacting system, we develop a gauge-invariant framework to compute $M_…
