Spin-Selective Second-Order Topological Insulators Enabling Cornertronics in 2D Altermagnets
Ning-Jing Yang, Zhigao Huang, Jian-Min Zhang
Recent progress in spintronics within the paradigm of altermagnets (AMs) opens new avenues for next-generation electronic device design. Here, we establish a spin-corner locking me…

Sliding Ferroelectrics Induced Hybrid-Order Topological Phase Transitions
Ning-Jing Yang, Jian-Min Zhang, Xiao-Ping Li +4
We propose ferroelectric layer sliding as a new approach to realize and manipulate topological quantum states in two-dimensional (2D) bilayer magnetic van der Waals materials. We s…

Hybrid-Order Topological Phase And Transition in 1H Transition Metal Compounds
Ning-Jing Yang, Zhigao Huang, Jian-Min Zhang
Inspired by recent experimental observations of hybrid topological states [Hossain et al. Nature 628, 527 (2024)], we predict hybrid-order topological insulators in 1H transition m…
