Quantum Hall physics: Hierarchies and conformal field theory techniques

TH Hansson, M Hermanns, SH Simon, SF Viefers - Reviews of Modern Physics, 2017 - APS
The fractional quantum Hall effect, being one of the most studied phenomena in condensed
matter physics during the past 30 years, has generated many ground-breaking new ideas …

Quantum Hall physics in rotating Bose–Einstein condensates

S Viefers - Journal of Physics: Condensed Matter, 2008 - iopscience.iop.org
The close theoretical analogy between the physics of rapidly rotating atomic Bose
condensates and the quantum Hall effect (ie a two-dimensional electron gas in a strong …

Disentangling entanglement spectra of fractional quantum Hall states on torus geometries

AM Läuchli, EJ Bergholtz, J Suorsa, M Haque - Physical review letters, 2010 - APS
We analyze the entanglement spectrum of Laughlin states on the torus and show that it is
arranged in towers, each of which is generated by modes of two spatially separated chiral …

Quantum hall system in tao-thouless limit

EJ Bergholtz, A Karlhede - Physical Review B—Condensed Matter and …, 2008 - APS
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

AM Läuchli, Z Liu, EJ Bergholtz, R Moessner - Physical Review Letters, 2013 - APS
We study the phase diagram of interacting electrons in a dispersionless Chern band as a
function of their filling. We find hierarchy multiplets of incompressible states at fillings ν= 1/3 …

[HTML][HTML] Generalized Devil's staircase and RG flows

A Flack, A Gorsky, S Nechaev - Nuclear Physics B, 2023 - Elsevier
We discuss a two-parameter renormalization group (RG) flow when parameters are
organized in a single complex variable, τ, with modular properties. Throughout the work we …

'One-dimensional'theory of the quantum Hall system

EJ Bergholtz, A Karlhede - Journal of Statistical Mechanics …, 2006 - iopscience.iop.org
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 …

Strange metal to insulator transitions in the lowest Landau level

B Currie, E Kozik - Physical Review Research, 2024 - APS
We study the microscopic model of electrons in the partially-filled lowest Landau level
interacting via the Coulomb potential by the diagrammatic theory within the GW …

Hall viscosity of hierarchical quantum Hall states

M Fremling, TH Hansson, J Suorsa - Physical Review B, 2014 - APS
Using methods based on conformal field theory, we construct model wave functions on a
torus with arbitrary flat metric for all chiral states in the abelian quantum Hall hierarchy …

Partons as unique ground states of quantum Hall parent Hamiltonians: The case of Fibonacci anyons

We present microscopic, multiple Landau level,(frustration-free and positive semi-definite)
parent Hamiltonians whose ground states, realizing different quantum Hall fluids, are parton …
