Research Abstract

Dynamic transport properties in hybrid systems with one-dimensional electrons made by edge states of quantum Hall effect and a quantum dot have been studied theoretically. It has been shown that strong electron-electron interaction causes quantum phase transition and that conventional theory cannot be applied to the resultant state as electron coherence is completely suppressed there. Decoherence effect of electron-electron interaction on single electron injection has also been evaluated. Current correlations in Kondo dots and Onsager's relations extended to non-equilibrium states have also been studied.
