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_…
Anderson localization: a density matrix approach
Ziyue Qi, Yi Zhang, Mingpu Qin +2
Anderson localization is a quantum phenomenon in which disorder localizes electronic wavefunctions. In this work, we propose a new approach to study Anderson localization based on…

Motivated by recent experiments on AVSb (A=K,Rb,Cs), the chiral flux phase has been proposed to explain time-reversal symmetry breaking. To fully understand the physics beh…
Gapless vortex bound states in superconducting topological semimetals
Yi Zhang, Shengshan Qin, Kun Jiang +1
We find that the vortex bound states in superconducting topological semimetals are gapless owing to topological massless excitations in their normal states. We demonstrate this uni…
Atomic line defects and topological superconductivity in unconventional superconductors
Yi Zhang, Kun Jiang, Fuchun Zhang +2
Topological superconductors (TSCs) are correlated quantum states with simultaneous off-diagonal long-range order and nontrivial topological invariants. They produce gapless or zero…
