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…
Quantized Topological States and Parity Anomaly in Intrinsic Quantum Anomalous Hall Insulator MnBi2Te4
Zhongxun Guo, Jingjing Gao, Zhiwei Huang +22
When thinned down to just a few atomic layers, the layered magnetic topological insulator MnBi2Te4 offers an exceptional platform for exploring a wide range of topological phenomen…
Orbital Description of Landau Levels
Huan Wang, Rui Shi, Zhaochen Liu +1
The pursuit of a lattice analogue for Landau levels has been a central theme in condensed matter physics. Although the correspondence between Chern bands and the lowest Landau leve…
Edge optical effect as a probe of chiral topological superconductors
Linghao Huang, Jing Wang
We study the optical effect of chiral topological superconductors in two dimensions. The linear optical response from chiral Bogoliubov edge modes in clean superconductors has in-g…
Layer-Dependent Quantum Anomalous Hall Effect in Rhombohedral Graphene
Zhaochen Liu, Jing Wang
The quantum anomalous Hall (QAH) effect, first proposed in the Haldane model, is a paradigmatic example of the application of band topology in condensed matter physics. The recent…
