Composite Fermion Insulator in Opposite-Fields Quantum Hall Bilayers
Ya-Hui Zhang
Recently several moiré super-lattice systems are proposed to host nearly flat Chern bands: the bands of the two valleys have opposite Chern numbers. In these systems the char…
Paired exciton condensate and topological charge- composite fermion pairing in half-filled quantum Hall bilayers
Ya-Hui Zhang, Itamar Kimchi
Half-filled Landau levels admit the theoretically powerful fermion-vortex duality but longstanding puzzles remain in their experimental realization as quantum Hall bilayers…
Bridging Hubbard Model Physics and Quantum Hall Physics in Trilayer Graphene/h-BN moiré superlattice
Ya-Hui Zhang, T. Senthil
The moiré superlattice formed by ABC stacked trilayer graphene aligned with a hexagonal boron nitride substrate (TG/h-BN) provides an interesting system where both the bandwidth an…
Nearly Flat Chern Bands in Moiré Superlattices
Ya-Hui Zhang, Dan Mao, Yuan Cao +2
Topology and electron interactions are two central themes in modern condensed matter physics. Here we propose graphene based systems where both the band topology and interaction ef…
Pair density wave, charge density wave and vortex in high Tc cuprates
Zhehao Dai, Ya-Hui Zhang, T. Senthil +1
A recent scanning tunneling microscopy (STM) experiment reports the observation of charge density wave (CDW) with period of approximately 8a in the halo region surrounding the vort…
