Abstract in another language

We present a theoretical analysis of Coulomb-correlation effects on the optical spectra of a single negatively charged quantum dot. The considered initial and final many particle states are adapted and motivated by a recent two-color pump-probe experiment. We demonstrate that the lowest energy transition is noticeably affected by exchange interactions if the initial state consists of a hot trion. It turns out that for initial states as obtained after spin-conserving carrier relaxation new absorption and emission lines emerge.
