Two-dimensional electron systems in a high magnetic field behave very strangely. They
exhibit rational fractional quantum numbers and contain exactly fractionally charged …

The edges of quantum Hall fluids behave as one-dimensional conductors. This article
reviews electron transport into these edge states, covering both the theory based on the …

We propose a particle-hole symmetric theory of the Fermi-liquid ground state of a half-filled
Landau level. This theory should be applicable for a Dirac fermion in the magnetic field at …

A two-dimensional electron system in an external magnetic field, with Landau-level filling
factor ν= 1/2, can be transformed to a mathematically equivalent system of fermions …

This book was first published in 2007. When electrons are confined to two dimensions,
cooled to near absolute zero temperature, and subjected to a strong magnetic field, they …

The development of the supersymmetry technique has led to significant advances in the
study of disordered metals and semiconductors. Proven of great use in the analysis of …

The Al x Ga 1− x As/GaAs heterostructure system is potentially of great importance for many
high-speed electronics and optoelectronic devices, because the lattice parameter difference …

The existence of a novel incompressible quantum liquid for spinless fermions at ν= 1/2 in the
Hall effect is suggested. This state is plausibly related by smooth extrapolation in quantum …

Today, more than 20 years after the discovery of the quantum Hall effect, the number of
publications in this field, at more than one paper per day, is still increasing. This remarkable …

We report the observation, for the first time, of a fractional quantum Hall state at ν= 1/2
Landau-level filling in a low disorder, double-layer electron system realized in a 680-Å-wide …
