Fractional quantum anomalous Hall effect in a singular flat band
Wenqi Yang, Dawei Zhai, Tixuan Tan +3
In the search of fractional quantum anomalous Hall (FQAH) effect, the conventional wisdom is to start from a flat Chern band isolated from the rest of the Hilbert space by band gap…

Magnetic and nematic order of Bose-Fermi mixtures in moiré superlattices of 2D semiconductors
Feng-Ren Fan, Tixuan Tan, Chengxin Xiao +1
We investigate the magnetic orders in a mixture of Boson (exciton) and Fermion (electron or hole) trapped in transition-metal dichalcogenides moiré superlattices. A sizable antife…
