Disentangling entanglement spectra of fractional quantum Hall states on torus geometries

Quantum hall system in tao-thouless limit
We consider spin-polarized electrons in a single Landau level on a torus. The quantum Hall
problem is mapped onto a one-dimensional lattice model with lattice constant 2 π/L 1, where …

Hierarchy of fractional Chern insulators and competing compressible states
We study the phase diagram of interacting electrons in a dispersionless Chern band as a

'One-dimensional'theory of the quantum Hall system
We consider the lowest Landau level on a torus as a function of its circumference L 1. When
L 1→ 0, the ground state at general rational filling fraction is a crystal with a gap—a Tao …
