A. Chekhovich et al., Phys. Rev. Lett. 104, 066804 (2010)] has demonstrated that high nuclear spin polarization can be achieved in self-assembled quantum dots by exploiting an optically forbidden transition between a heavy hole and a trion state. However, a fully polarized state is not achieved as expected from a classical rate equation. Here, we theoretically investigate this problem with the help of a quantum master equation and we demonstrate that a fully polarized state cannot be achieved due to formation of a nuclear dark state. Moreover, we show that the maximal degree of polarization depends on structural properties of the quantum dot.</dcterms:abstract> <dc:creator>Burkard, Guido</dc:creator> <dc:creator>Kavousanaki, Eleftheria</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2015-12-08T09:52:25Z</dc:date> <dc:language>eng</dc:language> <dcterms:issued>2014</dcterms:issued> <dc:contributor>Burkard, Guido</dc:contributor> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/32365"/> <dc:creator>Ribeiro, Hugo</dc:creator> </rdf:Description> </rdf:RDF>
