Optical Berry Curvature of Hinge State and Its Detection
Zheng Liu, Zhenhua Qiao, Yang Gao +1
We demonstrate that the topological hinge state can possess a nontrivial optical Berry curvature in the nonAbelian formulation of the Berry curvature. It can be readily probed by t…
Valley-polarized quantum anomalous Hall effect in van der Waals heterostructures based on monolayer jacutingaite family materials
Xudong Zhu, Yuqian Chen, Zheng Liu +2
We numerically study the general valley polarization and anomalous Hall effect in van der Waals (vdW) heterostructures based on monolayer jacutingaite family materials PtAX$_…
Layer Zero-Line Modes in Antiferromagnetic Topological Insulators
Wenhao Liang, Tao Hou, Junjie Zeng +3
Recently, the magnetic domain walls have been experimentally observed in antiferromagnetic topological insulators MnBiTe, where we find that the topological zero-line modes…
Second-Order Topological Insulator in van der Waals Heterostructures of CoBr/PtHgSe/CoBr
Zheng Liu, Yafei Ren, Yulei Han +2
Second-order topological insulator, which has (d-2)-dimensional topological hinge or corner states, has been observed in three-dimensional materials, but has yet not been observed…
Thickness-Driven Quantum Anomalous Hall Phase Transition in Magnetic Topological Insulator Thin Films
Yuchen Ji, Zheng Liu, Peng Zhang +9
The quantized version of anomalous Hall effect realized in magnetic topological insulators (MTIs) has great potential for the development of topological quantum physics and low-pow…
