Interaction-driven Quantum Anomalous Hall Effect in Halogenated Hematite Nanosheets
Qi-Feng Liang, Jian Zhou, Rui Yu +2
Based on first-principle calculations and model analysis, we show that the quantum anomalous Hall (QAH) insulating phase can be realized in the functionalized hematite (…
-Orbital Topological Insulator and Semimetal in Antifluorite CuS Family: Contrasting Spin Helicities, Nodal Box, and Hybrid Surface States
Xian-Lei Sheng, Zhi-Ming Yu, Rui Yu +2
We reveal a class of three-dimensional -orbital topological materials in the antifluorite CuS family. Derived from the unique properties of low-energy states, their…
Topologically protected Dirac plasmons in graphene
Deng Pan, Rui Yu, Hongxing Xu +1
Topological optical states exhibit unique immunity to defects and the ability to propagate without losses rendering them ideal for photonic applications.A powerful class of such st…
Spectroscopic evidence for bulk-band inversion and three-dimensional massive Dirac fermions in ZrTe5
Zhi-Guo Chen, R. Y. Chen, R. D. Zhong +8
Three-dimensional topological insulators (3D TIs) represent novel states of quantum matters in which surface states are protected by time-reversal symmetry and an inversion occurs…
From Nodal Chain Semimetal To Weyl Semimetal in HfC
Rui Yu, Quansheng Wu, Zhong Fang +1
Based on first-principles calculations and effective model analysis, we propose that the WC-type HfC, in the absence of spin-orbit coupling (SOC), can host a three-dimensional noda…
