Interlayer Coupling Induced Topological Phase Transition to Higher Order
Lizhou Liu, Jiaqi An, Yafei Ren +3
We theoretically find that the second-order topological insulator, i.e., corner states, can be engineered by coupling two copies of two-dimensional topological insul…
Tunning the number of chiral edge channels in a fixed quantum anomalous Hall system
Peng Deng, Yulei Han, Peng Zhang +3
Quantum anomalous Hall (QAH) insulators exhibit chiral edge channels characterized by vanishing longitudinal conductance and quantized Hall conductance of Ce2/h, wherein the Chern…
Disorder-Induced Phase Transitions in Three-Dimensional Chiral Second-Order Topological Insulator
Yedi Shen, Zeyu Li, Qian Niu +1
Topological insulators have been extended to higher-order versions that possess topological hinge or corner states in lower dimensions. However, their robustness against disorder i…
A unique van Hove singularity in kagome superconductor CsVTaSb with enhanced superconductivity
Yang Luo, Yulei Han, Jinjin Liu +23
Van Hove singularity (VHS) has been considered as a driving source for unconventional superconductivity. A VHS in two-dimensional (2D) materials consists of a saddle point connecti…
Berry-Curvature Engineering for Nonreciprocal Directional Dichroism in Two-Dimensional Antiferromagnets
Wenhao Liang, Junjie Zeng, Zhenhua Qiao +2
In two-dimensional antiferromagnets, we identify the mixed Berry curvature as the geometrical origin of the nonreciprocal directional dichroism (NDD), which refers to the differenc…
Sensing orbital hybridization of graphene-diamond interface with a single spin
Yucheng Hao, Zhiping Yang, Zeyu Li +13
Interfacial interactions are crucial in a variety of fields and can greatly affect the electric, magnetic, and chemical properties of materials. Among them, interface orbital hybri…
