Electric and magnetic fields tuned spin-polarized topological phases in two-dimensional ferromagnetic MnBiTe
Shi Xiao, Xiaoliang Xiao, Fangyang Zhan +3
Applying electric or magnetic fields is widely used to not only create and manipulate topological states but also facilitate their observations in experiments. In this work, we sho…
Floquet Valley-Polarized Quantum Anomalous Hall State in Nonmagnetic Heterobilayers
Fangyang Zhan, Zhen Ning, Li-Yong Gan +3
The valley-polarized quantum anomalous Hall (VQAH) state, which forwards a strategy for combining valleytronics and spintronics with nontrivial topology, attracts intensive interes…
Magnetic field induced Valley-Polarized Quantum Anomalous Hall Effects in Ferromagnetic van der Waals Heterostructures
Fangyang Zhan, Baobing Zheng, Xiaoliang Xiao +3
The valley-polarized quantum anomalous Hall effect (VQAHE) attracts intensive interest since it uniquely combines valleytronics and spintronics with nontrivial band topology. Here,…
Symmorphic and nonsymmorphic symmetries jointly-protected hourglass phonons
Baobing Zheng, Fangyang Zhan, Xiaozhi Wu +2
Hourglass dispersion is generally believed to be solely protected by nonsymmorphic symmetries, because these symmetries can introduce high-dimensional projective representations. H…
