  Recent experiments have demonstrated that for a quantum dot in an optical
resonator off-resonant cavity mode emission can occur even for detunings of the
order of 10 meV. We show that Coulomb mediated Auger processes based on
additional carriers in delocalized states can facilitate this far off-resonant
emission. Using a novel theoretical approach for a non-perturbative treatment
of the Auger-assisted quantum-dot carrier recombination, we present numerical
calculations of the far off-resonant cavity feeding rate and cavity mean photon
number confirming efficient coupling at higher densities of carriers in the
delocalized states. In comparison to fast Auger-like intraband scattering
processes, we find a reduced overall efficiency of Coulomb-mediated interband
transitions due the required electron-hole correlations for the recombination
processes.
