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…
Dynamics of fractional quantum Hall Liquids with a pulse at the edge
Jie Li, Chen-Xin Jiang, Zi-Xiang Hu
Motivated by recent experimental advancements in scanning optical stroboscopic confocal microscopy and spectroscopy measurements, which have facilitated exceptional energy-space-ti…
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…
The fractional quantum Hall nematics on the first Landau level in a tilted field
Dan Ye, Chen-Xin Jiang, Zi-Xiang Hu
We investigated the behavior of fractional quantum Hall (FQH) states in a two-dimensional electron system with layer thickness and an in-plane magnetic field. Our comparisons acros…
