Switchable axionic magnetoelectric effect via spin-flop transition in topological antiferromagnets
Yiliang Fan, Rongxiang Zhu, Tongshuai Zhu +3
The MnBiTe material family has emerged as a key platform for exploring magnetic topological phases, most notably exemplified by the experimental realization of the axion in…
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…
Unconventional superconductivity in ScIrSi by spin-orbit coupling driven flat band
Zhengyan Zhu, Yuxiang Wu, Shengtai Fan +6
The kagome lattice is very attractive as it can host many novel quantum states, such as the charge density wave, superconductivity, quantum spin liquid, etc. Meanwhile, iridates of…
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…
