Title: Kondo Effect in Quantum Dots

The resistance of a metal to an electric current usually drops if the temperature is lowered. However, a mysterious increase of the resistance of some metals at low temperatures was observed back in 1930s. Later, in 1960s, such behavior was associated with the peculiarities of the scattering of conduction electrons by localized magnetic moments. Attention to this low-temperature anomaly, the Kondo effect, persisted since then. Interest in it has peaked recently, since methods rooted in modern semiconductor technology gave experimentalists an unprecedented control over the Kondo systems. This talk reviews the theory and manifestations of the Kondo effect in the electron transport through very small conductors — quantum dots.
