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. DR.
