Three-dimensional quantum anomalous Hall effect in Weyl semimetals
Zhi-Qiang Zhang, Yu-Hang Li, Ming Lu +4
The quantum anomalous Hall effect (QAHE) is a quantum phenomenon in which a two-dimensional system exhibits a quantized Hall resistance in the absence of magnetic field, wh…
The fate of disorder in twisted bilayer graphene near the magic angle
Zhe Hou, Hailong Li, Qing Yan +2
In disordered lattices, itinerant electrons typically undergo Anderson localization due to random phase interference, which suppresses their motion. By contrast, in flat-band syste…
Topological Layer-Spin Filter in Screw Dislocation
Jiaojiao Zhou, Hong Hu, Jiangying Yu +3
While the quantum spin Hall effect leverages two-dimensional topological states to manipulate spin without dissipation, layertonics extends this paradigm to three dimension by enab…
Chern Vector Protected Three-dimensional Quantized Hall Effect
Zhi-Qiang Zhang, Shu-Guang Cheng, Hongfang Liu +3
Recently, Chern vector with arbitrary formula in three-dimensional systems has been experimentally realized [\…
