Scanning gate experiments: from strongly to weakly invasive probes
R. Steinacher, C. Pöltl, T. Krähenmann +8
An open resonator fabricated in a two-dimensional electron gas is used to explore the transition from strongly invasive scanning gate microscopy to the perturbative regime of weak…
Electron backscattering in a cavity: ballistic and coherent effects
A. A. Kozikov, D. Weinmann, C. Rossler +4
Numerous experimental and theoretical studies have focused on low-dimensional systems locally perturbed by the biased tip of a scanning force microscope. In all cases either open o…
Spin blockade in ground state resonance of a quantum dot
A. K. Huettel, H. Qin, A. W. Holleitner +5
We present measurements on spin blockade in a laterally integrated quantum dot. The dot is tuned into the regime of strong Coulomb blockade, confining ~ 50 electrons. At certain el…
Level Statistics and Localization for Two Interacting Particles in a Random Potential
Dietmar Weinmann, Jean-Louis Pichard
We consider two particles with a local interaction in a random potential at a scale (the one particle localization length). A simplified description is provided by a Gaus…
Signatures of electron correlations in the transport properties of quantum dots
Kristian Jauregui, Wolfgang Häusler, Dietmar Weinmann +1
The transition matrix elements between the correlated and electron states of a quantum dot are calculated by numerical diagonalization. They are the central ingredien…
--Oscillations for Correlated Electron Pairs in Disordered Mesoscopic Rings
D. Weinmann, A. Mueller-Groeling, J. -L. Pichard +1
The full spectrum of two interacting electrons in a disordered mesoscopic one--dimensional ring threaded by a magnetic flux is calculated numerically. For ring sizes far exceeding…
