Quantum-geometry stabilization of dilute fractional Chern insulators
Ying-Xing Ding, Li-Min Zhang, Wen-Tong Li +2
Fractional Chern insulators have attracted broad interest as lattice analogs of fractional quantum Hall states without Landau levels. However, low-filling fractional Chern insulato…

Fractional Chern insulator with higher Chern number in optical lattice
Ying-Xing Ding, Wen-Tong Li, Li-Min Zhang +4
Fractional Chern insulators arise in topologically nontrivial flat bands, characterized by an integer Chern number C that corresponds to the number of dissipationless edge states i…

Spin-Orbit Coupling-Driven Chirality Switching of Spin Waves in Altermagnets
Wen-Tong Li, Yu-Biao Wu, Lin Zhuang +2
Altermagnets host intrinsically chirality-splitting spin waves, which offer an ideal platform for chirality-based computing with low energy consumption and fast dynamics. However,…
