Bosonic Laughlin and Moore-Read states from non-Chern flat bands
Hongyu Lu, Wang Yao
The rapid advances in the study of fractional Chern insulators (FCIs) raise a fundamental question: while initially discovered in flat Chern bands motivated by their topological eq…
Probing Non-Fermi-Liquid Behaviour of Composite Fermi Liquid via Efficient Thermal Simulations
Bin-Bin Chen, Hongyu Lu, Zi Yang Meng
The physics of two-dimensional electron gas in a perpendicular magnetic field, i.e., the quantum Hall system, is remarkably rich. At half filling of the lowest Landau level, it has…
Interaction-induced nematic Dirac semimetal from quadratic band touching: A constrained-path quantum Monte Carlo study
Zi Hong Liu, Hongyu Lu, Zi Yang Meng +1
Electronic systems with quadratic band touchings, commonly found in two- and three-dimensional materials such as Bernal-stacked bilayer graphene, kagome metals, HgTe, and pyrochlor…
Fractional Chern insulator states in an isolated flat band of zero Chern number
Zuzhang Lin, Hongyu Lu, Wenqi Yang +2
A flat band with Chern number , and well isolated from the rest of Hilbert space by a gap much larger than interaction strength, is a context that has not been regarded as rel…
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…
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 $1…
