		Kondo Effect in Quantum Dots

In a quantum dot electrons are confined within a small region of space.
The confinement survives even if macroscopic conducting leads are attached
to the dot. Such a contact, however, establishes coherence between the
spin of the dot and spin system of the macroscopic conductor.  At low
temperature conduction electrons "screen" the dot's spin. This many-body
phenomenon is known as Kondo effect. It manifests itself spectacularly in
transport through a quantum dot: the conductance reaches the highest value
allowed by quantum mechanics. This talk is devoted to an introduction to
the Kondo physics in quantum dot systems.
