Abundant surface-semimetal phases in three-dimensional obstructed atomic insulators
Xianyong Ding, Xin Jin, Zhuo Chen +4
Three-dimensional obstructed atomic insulators (OAIs) are characterized by the appearance of floating surface states (FSSs) at specific surfaces. Benefiting from this feature, our…
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…
A Photoinduced Floquet Mixed-Weyl Semimetallic Phase in a Carbon Allotrope
Tingwei Deng, Baobing Zheng, Fangyang Zhan +3
The interplay between light and matter attracts tremendous interest for exploring novel topological quantum states and their phase transitions. Here we show by first-principles cal…
