Prediction of High-Temperature Half Quantum Anomalous Hall Effect in a Semi-magnetic Topological Insulator of MnBiTe/SbTe
M. U. Muzaffar, Kai-Zhi Bai, Wei Qin +6
The classic Thouless-Kohmoto-Nightingale-Nijs theorem dictates that a single electron band of a lattice can only harbor an integer quantum Hall conductance as a multiple of e^2/2h,…

Ferroelectrically Switchable Half-Quantized Hall Effect
M. U. Muzaffar, Kai-Zhi Bai, Wei Qin +5
Integrating ferroelectricity, antiferromagnetism, and topological quantum transport within a single material is rare, but crucial for developing next-generation quantum devices. He…

Topological Flat Minibands and Fractional Chern Insulators in Rashba Systems with Tunable Superlattice Potentials
Bokai Liang, Wei Qin, Zhenyu Zhang
Fractional Chern insulators are interaction-driven topological states that realize the lattice analogue of the fractional quantum Hall effect without external magnetic fields. Here…
