Scattering phase of quantum dots: Emergence of universal behavior    [PDF]

Rafael A. Molina, Rodolfo A. Jalabert, Dietmar Weinmann, Philippe Jacquod
We investigate scattering through chaotic ballistic quantum dots in the Coulomb blockade regime. Focusing on the scattering phase, we show that large universal sequences emerge in the short wavelength limit, where phase lapses of $\pi$ systematically occur between two consecutive resonances. Our results are corroborated by numerics and are in qualitative agreement with existing experiments.
