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…
Predicting Atomistic Transitions with Transformers
Henry Tischler, Wenting Li, Qi Tang +2
Accurate knowledge of the atomistic transition pathways in materials and material surfaces is crucial for many material science problems. However, conventional simulation technique…
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,…
