The influence of Coulomb-correlation effects as well as carrier relaxation on transient transmission change signals is investigated. Our model describes ultrafast disappearance of the fundamental trion absorption due to instantaneous Coulomb renormalizations and a delayed onset of gain at the same frequency, as found in the measurements. Going beyond previous experimental information, we predict that after spin-conserving carrier relaxation, new optical transitions exhibiting either gain or absorption should emerge that build up on a picosecond timescale. The time dependence of these new transitions provides insight into details of the carrier relaxation processes.</dcterms:abstract> <dcterms:issued>2011</dcterms:issued> <dc:contributor>Thomay, Tim</dc:contributor> <dc:contributor>D'Amico, Irene</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/19187"/> <dc:creator>Bratschitsch, Rudolf</dc:creator> <dc:contributor>Leitenstorfer, Alfred</dc:contributor> </rdf:Description> </rdf:RDF>
