Chern insulator phase realized in dual-gate-tuned MnBi2Te4 thin films grown by molecular beam epitaxy
Yunhe Bai, Yuanzhao Li, Ruixuan Liu +19
The intrinsic magnetic order, large topological-magnetic gap and rich topological phases make MnBi2Te4 a wonderful platform to study exotic topological quantum states such as axion…
Antiferromagnetic Quantum Anomalous Hall Effect Modulated by Spin Flips and Flops
Zichen Lian, Yongchao Wang, Yongqian Wang +11
The interplay between nontrivial band topology and layered antiferromagnetism in MnBi2Te4 has opened up a new avenue for exploring topological phases of matter. Representative exam…
Interplay between electronic dephasing and localization in finite-sized Chern insulator
Yunhe Bai, Yuanzhao Li, Jianli Luan +14
Anderson localization is anticipated to play a pivotal role in the manifestation of the quantum anomalous Hall effect, akin to its role in conventional quantum Hall effects. The si…
Second harmonic generation induced by gate voltage oscillation in few layer MnBi2Te4
Liangcai Xu, Zichen Lian, Yongchao Wang +7
Nonlinear charge transport, such as nonreciprocal longitudinal resistance and nonlinear Hall effect, has attracted considerable interest in probing the symmetries and topological p…
