``Quantum Chaos with Interactions:  Experiments in Quantum Dots''

Abstract:

This talk will present recent experiments on mesoscopic fluctuations in
quantum dots at low temperatures across the transition from open to
isolated quantum systems. At the transition from open to isolated,
conduction becomes dominated by tunneling, and individual
resonances become resolved. At this same point, Coulomb blockade of
conduction due to electron interactions appears,leading to periodic peaks
in conductance as the number of electrons on the dot changes.

Mesoscopic fluctuations persist in the nearly-isolated regime, and appear
well described by random matrix theory, A large separation of energy
scales allows a non-interacting random matrix theory to be applied to
this strongly interacting problem.

Finally, this discuss mesoscopic fluctuations of cotunneling, a coherent
virtual process. These new experimental results allow a direct
measurement of the tunneling time.
