Large cyclotron-resonance (CR) line splittings have been observed previously in two-dimensional (2D) electrons in AlGaN / GaN and in GaAs / AlGaAs heterojunctions. The features resemble a level anti-crossing and imply a strong interaction with an unk

A rotator, made from polycarbonate and operated hydraulically using liquid helium, has been developed at the High B/T Facility of the National High Magnetic Field Laboratory (NHMFL) in Gainesville, It can be tilted more than 90 degrees by applying a

Two-dimensional electron systems in a high magnetic field behave very strangely. They exhibit rational fractional quantum numbers and contain exactly fractionally charged particles. Electrons seem to absorb magnetic flux quanta, altering their statis

Low-temperature, electronic transport in Landau levels N>1 of a two-dimensional electron system is strongly anisotropic. At half-filling of either spin level of each such Landau level the magnetoresistance either collapses to form a deep minimum or i

This article provides a short review of recent developments in the area of the fractional quantum Hall effect. It attempts to provide some intuitively appealing images of the highly correlated electron behavior and the new quasi-particles it creates

The MBE double-growth technique that we call cleaved-edge overgrowth has, over the past several years, proved itself to be especially suitable for making quantum wires of the very highest quality. We will review our recent progress in measuring the t

We have determined the g factor of composite fermions (CF's) around Landau-level filling factor \ensuremath{\nu}= through angular-dependent thermal-activation energy measurements at several fractional quantum Hall states. The g factors agree to withi

One-dimensional structures are expected to show unique electronic transport behavior as a consequence of the Coulomb interaction between carriers. A considerable number of theoretical predictions remain largely untested by experiment due to a lack of

We have measured the transport properties of high-quality quantum wires fabricated in GaAs-AlGaAs by using cleaved edge overgrowth. The low temperature conductance is quantized as the electron density in the wire is varied. While the values of the co

Two-dimensional electrons in high magnetic field behave like new particles o which an even number of magnetic flux quanta has been attached. They are termed composite fermions. Several properties of composite fermions such as mass and ballistic motio
