We review the development of random-matrix theory (RMT) during the last fifteen years. We
emphasize both the theoretical aspects, and the application of the theory to a number of …

Theoretical approaches to one-dimensional and quasi-one-dimensional quantum rings with
a few electrons are reviewed. Discrete Hubbard-type models and continuum models are …

Mesoscopic physics refers to the physics of structures larger than a nanometer (one billionth
of a meter) but smaller than a micrometer (one millionth of a meter). This size range is the …

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 …

In this paper, we review some of the key concepts in ultrathin film magnetism which underpin
nanomagnetism. We survey the results of recent experimental and theoretical studies of well …

The ongoing miniaturization of solid state devices often leads to the question:“How small
can we make resistors, transistors, etc., without changing the way they work?” The question …

Making use of self-assembly techniques, we realize nanoscopic semiconductor quantum
rings in which the electronic states are in the true quantum limit. We employ two …

The creation of a suitable inorganic colloidal nanocrystal ink for use in a scalable coating
process is a key step in the development of low-cost solar cells. Here, we present a facile …

Nanometer-sized magnetic particles have generated continuous interest since the late
1940s because the study of their properties has proved to be scientifically and …

Quantum mechanics predicts that the equilibrium state of a resistive metal ring will contain a
dissipationless current. This persistent current has been the focus of considerable …
