Tunneling of quasiholes in the fractional quantum Hall regime
Moritz Helias, Daniela Pfannkuche
The elementary low energy excitations in the fractional quantum Hall (FQH) regime are known to be fractionally charged quasiparticles and quasiholes. This work focusses on quasihol…

Charge-localization and isospin-blockade in vertical double quantum dots
David Jacob, Bernhard Wunsch, Daniela Pfannkuche
Charge localization seems unlikely to occur in two vertically coupled symmetric quantum dots even if a small bias voltage breaks the exact isospin-symmetry of the system. However f…

Mapping of few-electron wave-functions in semiconductor nanocrystals - evidence of exchange interaction
Michael Tews, Daniela Pfannkuche
The influence of the tip-substrate bias induced electric field in a scanning-tunneling-spectroscopy experiment on charged InAs nanocrystals is studied. Calculating the ground and f…
