Revisiting quadratic band crossing: from interaction-driven instability to intrinsic topology
Yadong Jiang, Linghao Huang, Zhaochen Liu +2
The realization of robust quantum anomalous Hall (QAH) phases at elevated temperatures remains a central challenge in condensed matter physics. While quadratic band crossing points…
FeTaX2: A ferrimagnetic quantum anomalous Hall insulator
Yadong Jiang, Huan Wang, Jing Wang
We propose that the van der Waals layered ternary transition metal chalcogenides FeTa ( S, Se, Te) as a new family of ferrimagnetic quantum anomalous Hall insulators with…
Isolated nearly flat higher Chern band in monolayer transition metal trihalides
Kejie Bao, Huan Wang, Jiaxuan Guo +3
The interplay between non-trivial topology and strong electron interaction can generate a variety of exotic quantum matter. Here we theoretically propose that monolayer transition…
Design Topological Materials by Reinforcement Fine-Tuned Generative Model
Haosheng Xu, Dongheng Qian, Zhixuan Liu +2
Topological insulators (TIs) and topological crystalline insulators (TCIs) are materials with unconventional electronic properties, making their discovery highly valuable for pract…
Intrinsic antiferromagnetic topological insulator and axion state in V2WS4
Yadong Jiang, Huan Wang, Kejie Bao +1
Intrinsic magnetic topological insulators offers an ideal platform to explore exotic topological phenomena, such as axion electrodynamics, quantum anomalous Hall (QAH) effect and M…
