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…
