Theory of Correlated Hofstadter Spectrum in Magic-Angle Graphene
Chen Zhao, Zhaowen Miao, Zhen Ma +4
The magnetic-field-induced correlated Chern insulator (CCI) states in magic-angle twisted bilayer graphene (MATBG) have been intensively studied in experiments, but a simple and cl…
Hofstadter spectrum in a semiconductor moiré lattice
Chen Zhao, Ming Wu, Zhen Ma +4
Recently, the Hofstadter spectrum of a twisted heterobilayer has been observed in experiment [C. R. Kometter, et al. Nat.Phys.19, 1861 (2023)], but the orig…
Energy Spectrum Theory of Incommensurate Systems
Zhe He, Xin-Yu Guo, Zhen Ma +1
Due to the lack of the translational symmetry, calculating the energy spectrum of an incommensurate system has always been a theoretical challenge. Here, we propose a natural appro…
Local magnetic moment oscillation around an Anderson impurity on graphene
Shuai Li, Jin-Hua Gao
We theoretically investigate the spin resolved Friedel oscillation (FO) and quasiparticle interference (QPI) in graphene induced by an Anderson impurity. Once the impurity becomes…
