Chaos and Interactions in Quantum Dots

Abstract

Quantum dots are small conducting devices containing up to several thousand electrons. We focus here on closed dots whose single-electron dynamics are mostly chaotic. The mesoscopic fluctuations of the conduction properties of such dots reveal the effects of one-body chaos, quantum coherence and electron-electron interactions.Comment: 10 pages, including 11 figures, to appear in the Proceedings of the Nobel Symposium on Quantum Chaos 2000, Backaskog Castle, Sweden (Physica Scripta
