Quasisymmetry Enriched Gapless Criticality at Chern Insulator Transitions
Jiayu Li, Feng-Ren Fan, Wang Yao
In continuous topological phase transitions (CTPTs), the low-energy physics is governed by gap-closing subspaces, where approximate "higher" symmetries, termed quasisymmetries, may…
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…
Intrinsic Dipole Hall effect in twisted MoTe: magnetoelectricity and contact-free signatures of topological transitions
Feng-Ren Fan, Cong Xiao, Wang Yao
We discover an intrinsic dipole Hall effect in a variety of magnetic insulating states at integer fillings of twisted MoTe moiré superlattice, including topologically trivial a…
