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 antifer…
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…
Electrostatic moiré potential from twisted-hBN layers
Dong Seob Kim, Roy C. Dominguez, Rigo Mayorga-Luna +17
Moiré superlattices formed by vertically stacking van der Waals layers host a rich variety of correlated electronic phases and function as novel photonic materials. The moiré poten…
Anomalous Bloch oscillation and electrical switching of edge magnetization in bilayer graphene nanoribbon
Tixuan Tan, Fengren Fan, Ci Li +1
Graphene features topological edge bands that connect the pair of Dirac points through either sectors of the 1D Brillouin zone depending on edge configurations (zigzag or bearded).…
Edge state in AB-stacked bilayer graphene and its correspondence with SSH ladder
Tixuan Tan, Ci Li, Wang Yao
We study edge states in AB-stacked bilayer graphene (BLG) ribbon where the Chern number of the corresponding two-dimensional (2D) bulk Hamiltonian is zero. The existence and topolo…
