Phase Coherent Transport and Use of Feedback in Ballistic GaAs/AlGaAs Microstructures

Abstract

The aim of the funded research has been to investigate the use of feedback in phase-coherent electronic systems. Quantum dots afford the most controllable quantum system presently being investigated, because DC voltages applied to gates control the confining potentials that form the system. Over the course of the funding cycle, discoveries were made concerning the sensitivity of quantum dots to external perturbation, universal theoretical laws for quantum chaotic systems, and the crossover from open to closed quantum systems, the relation between ground and excited states, and the sensitivity of phase coherence to external radiation. Overall, 10 Physical Review Letters, 2 Science Papers, and 1 Applied Physics Letter were among the papers published that were supported by this grant.
