Chiral Graviton Modes in Non-Abelian lattice Fractional Quantum Hall states
Zeno Bacciconi, Min Long, Hernan Xavier +3
Synthetic quantum matter provides a highly tunable route to fractional quantum Hall physics beyond the constraints of conventional electronic materials. However, previous theoretic…
Chiral Graviton Modes in Fermionic Fractional Chern Insulators
Min Long, Zeno Bacciconi, Hongyu Lu +3
Chiral graviton modes are hallmark collective excitations of Fractional Quantum Hall (FQH) liquids. However, their existence on the lattice, where continuum symmetries that protect…
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…
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…
Collective excitations in chiral spin liquid: chiral roton and long-wavelength nematic mode
Hongyu Lu, Wei Zhu, Wang Yao
Chiral spin liquid (CSL) is a magnetic analogue of the fractional quantum Hall (FQH) liquid. Collective excitations play a vital role in shaping our understanding of these exotic q…
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…
