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…
