Emergent low-energy many-body Hilbert spaces in Chern bands
Chen-Xin Jiang, Zi-Xiang Hu, Bo Yang
We show that in Landau levels and more generic Chern bands, the most relevant many-body subspace selected by realistic two-body interactions alone (e.g., in the limit of vanishing…
Flat bands on spherical surface: from Landau levels to giant-quantum-number orbitals
Chen-Xin Jiang, Zi-Xiang Hu, Bo Yang
Flat bands result in a divergent density of states and high sensitivity to interactions in physical systems. While such bands are well known in systems under magnetic fields, their…
Superlattice induced electron percolation within a single Landau level
Nilanjan Roy, Bo Peng, Bo Yang
We investigate the quantum Hall effect in a single Landau level in the presence of a square superlattice of -function potentials. The interplay between the superlattice spacing…
Geometric Fluctuation of Conformal Hilbert Spaces and Multiple Graviton Modes in Fractional Quantum Hall Effect
Yuzhu Wang, Bo Yang
Neutral excitations in fractional quantum Hall (FQH) fluids define the incompressibility of topological phases, a species of which can show graviton-like behaviors and are thus cal…
