Shot noise of photon-excited electron-hole pairs in open quantum dots

Abstract
We investigate shot noise of photon-excited electron-hole pairs in open multiterminal, multichannel chaotic dots. Coulomb interactions in the dot are treated self-consistently giving a gauge-invariant expression for the finite frequency correlations. The Coulomb interactions decrease the noise; the strong interaction limit coincides with the noninteracting adiabatic limit. Inelastic scattering and dephasing in the dot are described by voltage and dephasing probe models, respectively. We find that dephasing leaves the noise invariant, but inelastic scattering decreases correlations eventually down to zero.
