Author(s): Bo Peng, Yuzhu Wang, and Bo Yang A single Landau level (LL) dressed with periodic electrostatic potentials can realize a plethora of interacting topological phases where the Hall conductivity generally does not equal to the LL filling factor. Their physics can be captured by a new family of flat topological bands: decorated Landau … [Phys. Rev. Lett. 137, 096601] Published Tue Aug 25, 2026
