Determine the chirality of Weyl fermions from the circular dichroism spectra of time-dependent ARPES
Rui Yu, Hongming Weng, Zhong Fang +2
We show that the intensity of pumped states near Weyl point is different when pumped with left- and right-handed circular polarized light, which leads to a special circular dichroi…
Topological Node-Line Semimetal in Compressed Black Phosphorus
Jianzhou Zhao, Rui Yu, Hongming Weng +1
Based on first-principles calculations and tight-binding model analysis, we propose that black phosphorus (BP) can host a three-dimensional topological node-line semimetal state un…
Quantum anomalous Hall effect and related topological electronic states
Hongming Weng, Rui Yu, Xiao Hu +2
Over a long period of exploration, the successful observation of quantized version of anomalous Hall effect (AHE) in thin film of magnetically-doped topological insulator completed…
Topological Nodal Line Semimetal and Dirac Semimetal State in Antiperovskite CuPdN
Rui Yu, Hongming Weng, Zhong Fang +2
Based on first-principles calculation and effective model analysis, we propose that the cubic antiperovskite material CuPdN can host a three-dimensional (3D) topological nodal…
