Generic integer and fractional quantum anomalous Hall crystals from interaction-driven band folding
Hongyu Lu, Han-Qing Wu, Bin-Bin Chen +2
Among the extensive studies of fractional quantum anomalous Hall (FQAH) states, there recently appears a growing interest in the topological states with coexisting charge density w…
Local spectroscopy of loop current order with individual magnetic atoms
Jiangchang Zheng, Caiyun Chen, Xu Zhang +16
Hidden ordered states--characterized by order parameters that elude conventional probes--pose a fundamental challenge for their identification in quantum materials. Recent experime…
Spectra of Magnetoroton and Chiral Graviton Modes of Fractional Chern Insulator

The roton-triggered charge-density-wave (CDW)is widely studied in fractional quantum Hall (FQH) and fractional Chern insulator (FCI) systems, and there also exist field theoretical…
Continuous Transition between Bosonic Fractional Chern Insulator and Superfluid
Hongyu Lu, Han-Qing Wu, Bin-Bin Chen +1
The properties of fractional Chern insulator (FCI) phases and the phase transitions between FCI and Mott insulators (MI) in bosonic systems are well studied. The continuous transit…
Continuous transition and gapless roton inside fractional quantum anomalous Hall states

From Fractional Quantum Anomalous Hall Smectics to Polar Smectic Metals: Nontrivial Interplay Between Electronic Liquid Crystal Order and Topological Order in Correlated Topological Flat Bands
Hongyu Lu, Han-Qing Wu, Bin-Bin Chen +2
Symmetry-breaking orders can not only compete with each other, but also be interwined, and the interwined topological and symmetry-breaking orders make the situation more intriguin…
