Probing a Kondo correlated quantum dot with spin spectroscopy
D. Kupidura, M. C. Rogge, M. Reinwald +2
We investigate Kondo effect and spin blockade observed on a many-electron quantum dot and study the magnetic field dependence. At lower fields a pronounced Kondo effect is found wh…
Mesoscopic BCS pairing in the repulsive 1d-Hubbard model
Luigi Amico, Andrea Mastellone, Andreas Osterloh
We study mesoscopic pairing in the one dimensional repulsive Hubbard model and its interplay with the BCS model in the canonical ensemble. The key tool is comparing the Bethe ansat…
UV light-induced atom desorption for large rubidium and potassium magneto-optical traps
C. Klempt, T. van Zoest, T. Henninger +4
We show that light-induced atom desorption (LIAD) can be used as a flexible atomic source for large Rb-87 and K-40 magneto-optical traps. The use of LIAD at short wavelengths allow…
Coupling symmetry of quantum dot states
M. C. Rogge, B. Harke, C. Fricke +4
With non-invasive methods, we investigate ground and excited states of a lateral quantum dot. Charge detection via a quantum point contact is used to map the dot dynamics in a regi…
Splitting and merging an elongated Bose-Einstein condensate at finite temperature
A. Mebrahtu, A. Sanpera, M. Lewenstein
We analyze coherence effects during the splitting of a quasi one-dimensional condensate into two spatially separated ones and their subsequent merging into a single condensate. Our…
A Continuous Field of C*-algebras and the Tangent Groupoid for Manifolds with Boundary
Johannes Aastrup, Ryszard Nest, Elmar Schrohe
For a smooth manifold with boundary we construct a semigroupoid and a continuous field of C*-algebras which extend Connes' construction of the tangent groupoid. We show the asympto…
