Quantum simulation of honeycomb lattice model by high-order moiré pattern
Qiang Wan, Chunlong Wu, Xun-Jiang Luo +11
Moiré superlattices have become an emergent solid-state platform for simulating quantum lattice models. However, in single moiré device, Hamiltonians parameters like lattice consta…
Moiré Assisted Fractional Quantum Hall State Spectroscopy
Fengcheng Wu, A. H. MacDonald
Intra-Landau level excitations in the fractional quantum Hall regime are not accessible via optical absorption measurements. We point out that optical probes are enabled by the per…
Observation of a Nematic Quantum Hall Liquid on the Surface of Bismuth
Benjamin E. Feldman, Mallika T. Randeria, András Gyenis +5
Nematic quantum fluids with wavefunctions that break the underlying crystalline symmetry can form in interacting electronic systems. We examine the quantum Hall states that arise i…
Microscopic Theory of Equilibrium Polariton Condensates
Fei Xue, Fengcheng Wu, Ming Xie +2
We present a microscopic theory of the equilibrium polariton condensate state of a semiconductor quantum well in a planar optical cavity. The theory accounts for the adjustment of…
SO(5) symmetry in the quantum Hall effect in graphene
Fengcheng Wu, Inti Sodemann, Yasufumi Araki +2
Electrons in graphene have four flavors associated with low-energy spin and valley degrees of freedom. The fractional quantum Hall effect in graphene is dominated by long-range Cou…
