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…
Vestigial Gapless Boson Density Wave Emerging between Fractional Chern Insulator and Finite-Momentum Supersolid
Hongyu Lu, Han-Qing Wu, Bin-Bin Chen +1
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 and gapless roton inside fractional quantum anomalous Hall states
Hongyu Lu, Han-Qing Wu, Bin-Bin Chen +1
Collective excitations play a vital role in understanding the exotic phases of matter and phase transitions in quantum many-body systems. For the first time, we numerically (via ex…
Spectra of Magnetoroton and Chiral Graviton Modes of Fractional Chern Insulator
Min Long, Hongyu Lu, Han-Qing Wu +1
Employing the state-of-the-art time-dependent variational principle (TDVP) algorithm, we compute the spectra of charge-neutral excitations in the (bosonic) \updated{ and $…
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…
