The purpose of this review is to survey the status of the theory and experiment which can
contribute to our knowledge of plasmon excitations in synthetic semiconductor …

We present data on the low-frequency noise of the high-field conducting state in the
insulating phase around the 1/5 fractional quantum Hall liquid at B= 11.9 T and how it …

Photoemission and tunnelling spectroscopies measure the energies at which single
electrons can be added to or removed from an electronic system. Features observed in such …

The experimental discovery of the fractional quantum Hall effect (FQHE) at the end of 1981
by Tsui, Stormer and Gossard was absolutely unexpected since, at this time, no theoretical …

We examine the dynamics of driven classical Wigner solids interacting with quenched
disorder from charged impurities. For strong disorder, the initial motion is plastic, in the form …

We present a calculation of the dispersion relation of the intra-Landau-level and inter-
Landau-level collective modes of the two-dimensional Wigner crystal in a strong magnetic …

We study the effects of weak disorder on a Wigner crystal in a magnetic field. We show that
an elastic description of the pinned Wigner crystal provides an excellent framework to obtain …

The physics of itinerant electrons in condensed matter is by and large governed by repulsive
Coulomb forces. However, attractive interactions may emerge and prevail in determining the …

Abstract Working in the Hartree-Fock approximation, we calculate the ground-state energy of
different states of the two-dimensional electron gas in a double-quantum-well system as a …

We investigate the dynamics of a two-dimensional electron system in a high magnetic field
in the Wigner-crystalline regime where charge-density-wave correlations extend over a …
