Scattering phase of quantum dots: Emergence of universal behavior
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 π systematically occur between two consecutive resonances. Our result...

| Summary: | 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 Ï€ systematically occur between two consecutive resonances. Our results are corroborated by numerics and are in qualitative agreement with existing experiments. © 2012 American Physical Society. |
