A quantum criticality perspective on the charging of narrow quantum-dot levels
V. Kashcheyevs, C. Karrasch, T. Hecht +3
Understanding the charging of exceptionally narrow levels in quantum dots in the presence of interactions remains a challenge within mesoscopic physics. We address this fundamental…
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…
