Spin-chirality-dependent modulation of topological gap, Chern number, and valley-polarization in monolayer kagome lattice Cr3Se4
Wenzhe Zhou, Guibo Zheng, Yating Li +2
Kagome materials exhibit unique electronic properties, such as the quantum anomalous Hall effect. The control of Chern numbers is critical for quantum device manipulation, but exis…

Quantum spin Hall effect protected by spin U(1) quasisymmetry
Lu Liu, Yuntian Liu, Jiayu Li +2
Quantum spin Hall (QSH) effect, where electrons with opposite spin channels are deflected to opposite sides of a two-dimensional system with a quantized conductance, was believed t…

Orbital doublet driven even-spin Chern insulators
Lu Liu, Yuntian Liu, Jiayu Li +2
Quantum spin Hall insulators hosting edge spin currents hold great potential for low-power spintronic devices. In this paper, we present a universal approach to achieve a high and…
