The spin–orbit coupling plays the role of a tunable spin rotator and can be controlled via a gate electrode on top of the conductor. We use spin-resolved scattering theory to calculate the zero-temperature current fluctuations (shot noise) for such a four-terminal device and show that the shot noise is proportional to the spin polarization of the source. Moreover, we analyze the effect of spin–orbit-induced intersubband coupling, leading to an additional spin rotation.</dcterms:abstract> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/29150"/> <dc:contributor>Egues, Jose C.</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2014-10-21T08:45:52Z</dc:date> <dc:contributor>Loss, Daniel</dc:contributor> <dcterms:issued>2003</dcterms:issued> <dc:creator>Egues, Jose C.</dc:creator> <dc:contributor>Burkard, Guido</dc:contributor> <dc:creator>Loss, Daniel</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2014-10-21T08:45:52Z</dcterms:available> </rdf:Description> </rdf:RDF>
