Midgap states induced by Zeeman field and wave superconductor pairing
Yuanjun Jin, XingYu Yue, Yong Xu +2
The one-dimensional Su-Schrieffer-Heeger (SSH) model is central to band topology in condensed matter physics, which allows us to understand and design distinct topological states.…
Three consecutive quantum anomalous Hall gaps in a metal-organic network
Xiang-Long Yu, Tengfei Cao, Rui Wang +2
In the quantum anomalous Hall (QAH) effect, chiral edge states are present in the absence of magnetic fields due to the intrinsic band topology. In this work, we predict that a syn…
Possible high-temperature magnetically topological material MnBiTe
Wen-Feng Wu, Han-Yu Wang, Wei-Hua Wang +4
The Mn-Bi-Te family displaying magnetism and non-trivial topological properties has received extensive attention. Here, we predict that the antiferromagnetic structure of MnB…
Direct Measurement of Topological Number by Quench Dynamics
Pei-Ling Huang, Chao Ma, Xiang-Long Yu +1
The measurement of topological number is crucial in the research of topological systems. Recently, the relations between the topological number and the dynamics are built. But a di…
Quantum dynamical characterization and simulation of topological phases with high-order band inversion surfaces
Xiang-Long Yu, Wentao Ji, Lin Zhang +3
How to characterize topological quantum phases is a fundamental issue in the broad field of topological matter. From a dimension reduction approach, we propose the concept of high-…
From a normal insulator to a topological insulator in plumbene
Xiang-Long Yu, Li Huang, Jiansheng Wu
Plumbene, similar to silicene, has a buckled honeycomb structure with a large band gap ( meV). All previous studies have shown that it is a normal insulator. Here, we per…
