Publisher Summary Quantum transport is conveniently studied in a two-dimensional
electron gas (2DEG) because of the combination of a large Fermi wavelength and large …

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 …

A method is described for the numerical calculations of the ballistic conductance in
mesoscopic structures in magnetic fields within a lattice model. Examples of calculated …

We report detailed measurements of the low-temperature magnetoconductance in ballistic
microstructures in the shape of a ''chaotic''stadium and a circle with quantum-point-contact …

We develop a novel formulation of dc electrical linear-response theory for a phase-coherent
conductor with multiple leads valid in arbitrarily strong magnetic field and for a given impurity …

A model for ballistic transport based on classical mechanics of electrons at the Fermi level is
shown to exhibit a variety of magnetoresistance anomalies found experimentally in narrow …

We have performed quantum-mechanical and classical calculations of the magnetotransport
behavior of two-dimensional four-terminal junctions in the ballistic regime. Experimentally …

An asymmetric artificial scatterer in a semiconductor microjunction is shown to dramatically
affect the nonlinear transport of ballistic electrons. The chosen device geometry, defined in a …

We present analytical calculations of the potential in a two-dimensional electron gas (2DEG)
generated by patterned polygon gates on the surface of a heterostructure. They give the …

Reflection of microwaves from a cavity is measured in a frequency domain where the
underlying classical chaotic scattering leaves a clear mark on the wave dynamics. We check …
