We find that the Josephson current switches abruptly from a p- to a 0-phase as the coupling increases. At intermediate couplings the total spin in the ground state depends on the phase difference between the two superconductors. Our numerical results can explain the crossover in the conductance observed experimentally by Buitelaar et al. [Phys. Rev. Lett. 89, 256801 (2002)].</dcterms:abstract> <dc:creator>Choi, Mahn-Soo</dc:creator> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/5267/1/Kondo_effect_and_Josephson_current_through_a_quantum_dot_between_two_superconductors.pdf"/> <dcterms:title>Kondo effect and Josephson current through a quantum dot between two superconductors</dcterms:title> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/5267/1/Kondo_effect_and_Josephson_current_through_a_quantum_dot_between_two_superconductors.pdf"/> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:54:30Z</dcterms:available> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:54:30Z</dc:date> <dc:format>application/pdf</dc:format> <dc:rights>Attribution-NonCommercial-NoDerivs 2.0 Generic</dc:rights> <dc:contributor>Lee, Minchul</dc:contributor> <dc:creator>Lee, Minchul</dc:creator> <dcterms:rights rdf:resource="http://creativecommons.org/licenses/by-nc-nd/2.0/"/> </rdf:Description> </rdf:RDF>
