We distinguish between the various spin configurations and calculate the low-energy biexciton spectrum using the Heitler-London approximation as a function of magnetic and electric fields. The oscillator strengths for the biexciton recombination involving the sequential emission of two photons are calculated. The entanglement of the polarizations resulting from the spin configuration in the biexciton states is quantified as a function of the photon emission angles.</dcterms:abstract> <dcterms:title>Biexcitons in coupled quantum dots as a source of entangled photons</dcterms:title> <dc:date rdf:datatype="">2011-03-24T14:53:43Z</dc:date> <dcterms:hasPart rdf:resource=""/> <bibo:uri rdf:resource=""/> <dc:creator>Burkard, Guido</dc:creator> <dc:contributor>Loss, Daniel</dc:contributor> <dc:contributor>Gywat, Oliver</dc:contributor> </rdf:Description> </rdf:RDF>
