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,…

Alternating-Chiral Charge Density Waves and Hybrid Ferrimagnetism in Monolayered NbTe2
Yusong Bai, Guohua Cao, Jinghao Deng +12
Intertwining of different quantum degrees of freedom manifests exotic quantum phenomena in many-body systems, especially in reduced dimensionality. Here we show that monolayered Nb…
