Quantum dots, sometimes called artificial atoms, are exquisite
tools by which quantum behavior can be probed on a larger scale
than the atomic, namely on the nanometer scale. While the physics
exhibited by these devices is closer to classical than atomic
physics, quantum dots are still sufficiently small to clearly
exhibit quantum phenomena. This volume, intended for graduate
students and young researchers, offers an introduction to many of
these fascinating aspects. In the first lecture, R. Shankar treats
the general theoretical aspects of Fermi liquids, in particular the
renormalization group approach, and then applies this to large
quantum dots. A completely different approach is encountered in the
second contribution, by J.M. Elzerman et al., which thoroughly
details current and likely experimental developments in the study
of small quantum dots. Here the emphasis lies on the electron spin
which is to be used as a qubit. In the third lecture series, by M.
Pustilnik and Leonid I. Glazman, mechanisms of low-temperature
electronic transport through a quantum dot -- weakly coupled to two
conducting leads -- are reviewed. The fourth and final lecture
series, by C.W.J. Beenakker, deals with a peculiar property of
superconducting mirrors, a very interesting aspect of nanophysics
discovered by Andreev about forty years ago and still a challenge
to experimental physicists.
