Photoconductance of a one-dimensional quantum dot
M. Vicari, A. Braggio, E. Galleani d'Agliano +1
The ac-transport properties of a one-dimensional quantum dot with non-Fermi liquid correlations are investigated. It is found that the linear photoconductance is drastically influe…
Transport in quantum wires with impurities at finite temperatures
T. Kleimann, M. Sassetti, B. Kramer
The temperature dependence of Coulomb blockade peaks of a one dimensional quantum dot is calculated. The Coulomb interaction is treated microscopically using the Luttinger liquid m…
Fractal fluctuations in quantum integrable scattering
Italo Guarneri, Marcello Terraneo
We theoretically and numerically demonstrate that completely integrable scattering processes may exhibit fractal transmission fluctuations, due to typical spectral properties of in…
Field-induced Coulomb coupling in semiconductor macroatoms: application to "single-electron" quantum devices
I. D'Amico, F. Rossi
A novel approach for the control of exciton-exciton Coulomb coupling in semiconductor macroatoms/molecules is proposed. We show that by applying properly tailored external fields,…
Quantum phases in artificial molecules
Massimo Rontani, Filippo Troiani, Ulrich Hohenester +1
The many-body state of carriers confined in a quantum dot is controlled by the balance between their kinetic energy and their Coulomb correlation. In coupled quantum dots, both can…
Quantum algorithms for Josephson networks
Jens Siewert, Rosario Fazio
We analyze possible implementations of quantum algorithms in a system of (macroscopic) Josephson charge qubits. System layout and parameters to realize the Deutsch algorithm with u…
Quantum-information processing in semiconductor quantum dots
Filippo Troiani, Ulrich Hohenester, Elisa Molinari
We propose an all-optical implementation of quantum-information processing in semiconductor quantum dots, where electron-hole excitations (excitons) serve as the computational degr…
Monitoring Single Scattering Events in Single Quantum Dots
Ulrich Hohenester
The quantum-jump approach is used for a theoretical description of resonance luminescence from a {\em single} semiconductor quantum dot in contact with its solid-state environment.…
Compensation of the spin of a quantum dot at Coulomb blockade
Domenico Giuliano, Benoit Jouault, Arturo Tagliacozzo
We discuss a new entangled state that has been observed in the conduction across a quantum dot. At Coulomb blockade, electrons from the contacts correlate strongly to those localiz…
Optical excitations of a self assembled artificial ion
F. Findeis, M. Baier, A. Zrenner +4
By use of magneto-photoluminescence spectroscopy we demonstrate bias controlled single-electron charging of a single quantum dot. Neutral, single, and double charged excitons are i…
Possibility of two-channel orbital Kondo "spin" 1/2 conductance in a quantum dot
Domenico Giuliano, Benoit Jouault, Arturo Tagliacozzo
We propose that two-channel orbital Kondo ``spin'' 1/2 conductance can be measured in a quantum dot at Coulomb Blockade with an odd number of electrons with contacts in a pillar co…
