Abstract

A many-body theory for quantum coherence in a semiconductor quantum-dot system is presented. We present the theory in detail for a scheme in a InGaAs-GaAs quantum dot with a pulsed drive field. The paper shows the significant differences in the predictions of this theory and those of an independent-particle treatment, adapted from atomic quantum coherence theory. Specifically, the influence of the quantum-dot level structure on group-velocity slowdown is discussed, and the influence of different Coulomb renormalization effects is analysed.
