Ab Initio Theory of Phonon Magnetic Moment Induced by Electron-Phonon Coupling in Magnetic Materials
Fuyi Wang, Xinqi Liu, Hong Sun +5
Circularly polarized phonons, characterized by nonzero angular momenta and magnetic moments, have attracted extensive attention. However, a long-standing critical issue in this fie…

Electrically tunable high-Chern-number quasiflat bands in twisted antiferromagnetic topological insulators
Huaiqiang Wang, Yiliang Fan, Haijun Zhang
Isolated flat bands with significantly quenched kinetic energy of electrons could give rise to exotic strongly correlated states from electron-electron interactions. More intriguin…

Symmetry-driven anisotropic coupling effect in antiferromagnetic topological insulator: Mechanism for high-Chern-number quantum anomalous Hall state
Yiliang Fan, Huaiqiang Wang, Peizhe Tang +4
Antiferromagnetic (AFM) topological insulators (TIs), which host magnetically gapped Dirac-cone surface states and exhibit many exotic physical phenomena, have attracted great atte…
