Scattering phase of quantum dots: emergence of universal behavior.
نویسندگان
چکیده
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 results are corroborated by numerics and are in qualitative agreement with existing experiments.

Quantum dots of CdS synthesized by micro-emulsion under ultrasound: size distribution and growth kinetics
Quantum dots of CdS with hexagonal phase were prepared at relatively low temperature (60 oC) and short time by micro-emulsion (O/W) under ultrasound. This study was focused on the particle size distribution and the growth kinetics. The particle size distribution obtained from the optical absorption edge. It was relatively symmetrical with sonication time. In addition, an agreement was observed ...
متن کاملPhase lapses in scattering through multi-electron quantum dots: Mean-field and few-particle regimes
We show that the observed evolution of the transmission phase through multi-electron quantum dots with more than ∼ 10 electrons, which shows a universal (i.e., independent of N) as yet unexplained behavior, is consistent with an electrostatic model, where electron-electron interaction is described by a mean-field approach. Moreover, we perform exact calculations for an open 1D quantum dot and s...
متن کاملShot noise in ballistic quantum dots with a mixed classical phase space.
We investigate shot noise for quantum dots whose classical phase space consists of both regular and chaotic regions. The noise is systematically suppressed below the universal value of fully chaotic systems, by an amount which varies with the positions of the leads. We analyze the dynamical origin of this effect by a novel way to incorporate diffractive impurity scattering. The dependence of th...
متن کاملMesoscopic to universal crossover of the transmission phase of multilevel quantum dots.
Transmission phase alpha measurements of many-electron quantum dots (small mean level spacing delta) revealed universal phase lapses by pi between consecutive resonances. In contrast, for dots with only a few electrons (large delta), the appearance or not of a phase lapse depends on the dot parameters. We show that a model of a multilevel quantum dot with local Coulomb interactions and arbitrar...
متن کاملInelastic Electron Lifetime in Disordered Mesoscopic Systems
Inelastic quasiparticle lifetime due to the electron-electron interaction (outscattering time in the kinetic equation formalism) is calculated for finite metallic diffusive systems (quantum dots) in the whole range of parameters. Both cases of “continuous” (the inelastic level broadening much exceeds the mean level spacing) and “discrete” spectrum are analyzed. In particular, crossover between ...
