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…
