The fractional quantum Hall effect [PDF]

open access: yesProceedings of the National Academy of Sciences, 1986
A review is given of the fractional quantum Hall effect with the emphasis placed on the basic experimental facts. Only a superficial description is made of the current theoretical understanding.

Quantum Hall effect: from the drude conductivity model to the Chern-Simons field description

open access: yesRevista Brasileira de Ensino de FĂ­sica, 2023
The goal of this article is to introduce the quantum Hall effect (QHE) from its classical roots to the quantum integer and fractional versions. This is a robust phenomenon with topological nature.

Dirac fermion spectrum of the fractional quantum Hall states

open access: yesCondensed Matter Physics, 2023
Applying a unified approach, we study the integer quantum Hall effect (IQHE) and fractional quantum Hall effect (FQHE) in the Hofstadter model with short range interactions between fermions.

Duality and the fractional quantum Hall effect [PDF]

open access: yesNuclear Physics B, 1995
The edge states of a sample displaying the quantum Hall effect (QHE) can be described by a 1+1 dimensional (conformal) field theory of $d$ massless scalar fields taking values on a $d$-dimensional torus. It is known from the work of Naculich, Frohlich et al.\@ and others that the requirement of chirality of currents in this \underline{scalar} field ...

Quantum skyrmion Hall effect in f-electron systems

open access: yesPhysical Review Research, 2023
The flow of electric current through a two-dimensional material in a magnetic field gives rise to the family of Hall effects. The quantum versions of these effects accommodate robust electronic edge channels and fractional charges.
