Ferroelectrically Controlled Chirality Switching of Weyl Quasiparticles
Zeling Li, Yu liu, Le Du +6
Weyl quasiparticles, as gapless low-energy excitations with nontrivial chirality, have garnered extensive interest in recent years. However, archieving effective and reversible con…
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…
Two-dimensional Dual-Switchable Ferroelectric Altermagnets: Altering Electrons and Magnons
ShuaiYu Wang, Wei-Wei Wang, Jiaxuan Fan +3
Ferroelectric altermagnets (FEAMs) offer unique magnetoelectric coupling properties by combining the characteristics of both antiferromagnets and ferromagnets, yet their multifunct…
Essentially degenerate hidden nodal lines in two-dimensional magnetic layer groups
Xiao-Ping Li, Chaoxi Cui, Lei Wang +4
According to the theory of group representations, the types of band degeneracy can be divided into accidental degeneracy and essential degeneracy. The essentially degenerate nodal…
