Experimental discovery of a quantized Hall state at 5/2 filling factor presented an enigmatic
finding in an established field of study that has remained an open issue for more than twenty …

Magnetotransport experiments on high mobility two-dimensional electron gases in
GaAs/AlGaAs heterostructures have revealed striking anomalies near half filling of several …

We consider the two lowest Landau levels at half filling. In the higher Landau level (ν= 5/2),
we find a first-order phase transition separating a compressible striped phase from a paired …

The fractional quantum Hall (FQH) effect emerges in high-quality two-dimensional electron
systems exposed to a magnetic field when the Landau-level filling factor, ν e, takes on a …

The observation of new insulating phases of two-dimensional electrons in the first excited
Landau level is reported. These states, which are manifested as reentrant integer quantized …

The phase diagram of an interacting two-dimensional electron system in a high magnetic
field is enriched by the varying form of the effective Coulomb interaction, which depends …

The ground-state phase diagram of 2D electrons in a high Landau level (index N= 2) is
studied by the density-matrix renormalization group method. Pair correlation functions are …

It is well known that there is a particle-hole symmetry for spin-polarized electrons with two-
body interactions in a partially filled Landau level, which becomes exact in the limit where …

We propose a quantum stripe (smectic) coupled-Luttinger-liquid model for the anisotropic
states which occur in two-dimensional electron systems with high-index partial Landau-level …

We report on numerical studies of two-dimensional electron systems in the presence of a
perpendicular magnetic field, with a high Landau level (index N≥ 2) half filled by electrons …
