Recent advances in exciton based quantum information processing in quantum dot nanostructures
H. J. Krenner, S. Stufler, M. Sabathil +6
Recent experimental developments in the field of semiconductor quantum dot spectroscopy will be discussed. First we report about single quantum dot exciton two-level systems and th…
Manipulation of the Spontaneous Emission Dynamics of Quantum Dots in 2D Photonic Crystals
A. Kress, F. Hofbauer, N. Reinelt +4
We demonstrate the ability to control the spontaneous emission dynamics of self-assembled quantum dots via the local density of optical modes in 2D-photonic crystals. We show that…
Direct Observation of Controlled Coupling in an Individual Quantum Dot Molecule
H. J. Krenner, M. Sabathil, E. C. Clark +5
We report the direct observation of quantum coupling in individual quantum dot molecules and its manipulation using static electric fields. A pronounced anti-crossing of different…
Kondo Effect in a Many-Electron Quantum Ring
A. Fuhrer, T. Ihn, K. Ensslin +2
The Kondo effect is investigated in a many-electron quantum ring as a function of magnetic field. For fields applied perpendicular to the plane of the ring a modulation of the Kond…
Observation of single defect relaxation in a freely suspended nano resonator
Florian W. Beil, Robert H. Blick, Achim Wixforth +3
Relaxation of single defects in a nanometer sized resonator is observed by coupling surface acoustic waves to a freely suspended beam. The surface waves act on the resonator as dri…
