Excitonic Chern insulator and kinetic ferromagnetism in MoTe/WSe moiré bilayer
Zhihuan Dong, Ya-Hui Zhang
We propose a new mechanism for quantum anomalous Hall (QAH) effect in the AB stacked MoTe/WSe system. Based on the observation that the inter-layer tunneling is suppressed…
Evolution between quantum Hall and conducting phases: simple models and some results
Zhihuan Dong, T. Senthil
Quantum many particle systems in which the kinetic energy, strong correlations, and band topology are all important pose an interesting and topical challenge. Here we introduce and…
Non-commutative field theory and composite Fermi Liquids in some quantum Hall systems
Zhihuan Dong, T. Senthil
Composite Fermi liquid metals arise at certain special filling fractions in the quantum Hall regime and play an important role as parent states of gapped states with quantized Hall…
Ferromagnetism in narrow bands of moiré superlattices
Cécile Repellin, Zhihuan Dong, Ya-Hui Zhang +1
Many graphene moiré superlattices host narrow bands with non-zero valley Chern numbers. We provide analytical and numerical evidence for a robust spin and/or valley polarized insul…
Bosonic Integer Quantum Hall States without Landau Levels on Square Lattice
Wanli Liu, Zhiyu Dong, Zhihuan Dong +3
We study an interacting two-component hard-core bosons on square lattice for which, in the presence of staggered magnetic flux, the ground state is a bosonic integer quantum Hall (…
