Phase lapses in transmission through interacting two-level quantum dots
C. Karrasch, T. Hecht, A. Weichselbaum +3
We investigate the appearance of pi lapses in the transmission phase theta of a two-level quantum dot with Coulomb interaction U. Using the numerical and functional renormalization…

Mesoscopic to universal crossover of transmission phase of multi-level quantum dots
C. Karrasch, T. Hecht, A. Weichselbaum +3
Transmission phase αmeasurements of many-electron quantum dots (small mean level spacing δ) revealed universal phase lapses by πbetween consecutive resonances. In contrast, for dot…

Tunability of qubit Coulomb interaction: Numerical analysis of top gate depletion in two-dimensional electron systems
A. Weichselbaum, S. E. Ulloa
We investigate the tunability of electrostatic coupling between solid state quantum dots as building blocks for quantum bits. Specifically, our analysis is based upon two-dimension…
