Optical Hall absorption sum rule and spectral compensation in time-reversal-breaking moiré and Hofstadter systems
Yixin Zhang, H. Huang
Optical spectroscopy provides a powerful, contact-free probe of topological quantum states, yet exact constraints on antisymmetric Hall absorption remain much less well developed t…

Evidence of competing ground states between fractional Chern insulator and antiferromagnetism in moiré MoTe2
Xumin Chang, Feng Liu, Fan Xu +18
Two-dimensional moire materials present unprecedented opportunities to explore quantum phases of matter arising from the interplay of band topology and strong correlations.One of t…

Interplay between topology and correlations in the second moiré band of twisted bilayer MoTe2
Fan Xu, Xumin Chang, Jiayong Xiao +17
Topological flat bands formed in two-dimensional lattice systems offer unique opportunity to study the fractional phases of matter in the absence of an external magnetic field. Cel…
