We address the question of how a variation of I_dc and hence of the microscopic phases of the electronic wave functions results in the observable global phase of the conductance oscillations. Whereas the first one can be varied continuously, the latter has to be quantized for a ring in a two-wire configuration by virtue of the Onsager symmetry relations. We observe a correlation between a phase flip by +/- π (pi) and the amplitude of the oscillations.</dcterms:abstract> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:52:37Z</dc:date> <dc:contributor>Häussler, Ralf</dc:contributor> <dc:creator>Löhneysen, Hilbert von</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:52:37Z</dcterms:available> <dc:language>eng</dc:language> <dcterms:issued>2001</dcterms:issued> <dc:creator>Weber, Heiko B.</dc:creator> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:format>application/pdf</dc:format> <dc:creator>Scheer, Elke</dc:creator> <dc:contributor>Scheer, Elke</dc:contributor> <dc:contributor>Löhneysen, Hilbert von</dc:contributor> <dc:rights>deposit-license</dc:rights> <dc:contributor>Weber, Heiko B.</dc:contributor> <dcterms:title>Conductance oscillations in mesoscopic rings : microscopic versus global phase</dcterms:title> <dc:creator>Häussler, Ralf</dc:creator> </rdf:Description> </rdf:RDF>
