Interference and interactions in open quantum dots
In this report, we review the results of our joint experimental and theoretical studies of electroninterference, and interaction, phenomena in open electron cavities known as quantum dots. The transport through these structures is shown to be heavily influenced by the remnants of their discrete density of states, elements of which remain resolved in spite of the strong coupling that exists betw...
متن کاملConductance in quantum wires by three quantum dots arrays
A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...

متن کاملPhonon affected transport through molecular quantum dots.
To describe the interaction of molecular vibrations with electrons at a quantum dot contacted to metallic leads, we extend an analytical approach that we previously developed for the many-polaron problem. Our scheme is based on an incomplete variational Lang-Firsov transformation, combined with a perturbative calculation of the electron-phonon self-energy in the framework of generalized Matsuba...
متن کاملTransport through Quantum Dots and Thekondo Problem
Transport through quantum dots with large level spacing and charging energy is considered. At low temperature and strong coupling to the leads, quantum uctuations and the Kondo eeect become important. They show up, e.g., as zero-bias anomalies in the current-voltage characteristics. We use a recently developed diagrammatic technique as well as a new real-time renormalization-group approach to d...
