We find that the Josephson junction can sustain multiple undamped Josephson oscillations up to a characteristic time scale tc without quasipartcles being excited in the system. This may explain recent related experiments. At larger times the dynamics of the junction is governed by fast Rabi oscillations between the descrete quasiparticle levels. We predict that a selftrapped BEC state will be destroyed by these Rabi oscillations.</dcterms:abstract> <dcterms:issued>2009</dcterms:issued> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/4652/1/Posazhennikova0903.5459v4.pdf"/> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/4652"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:49:17Z</dc:date> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dc:rights>terms-of-use</dc:rights> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:contributor>Trujillo-Martinez, Mauricio</dc:contributor> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/4652/1/Posazhennikova0903.5459v4.pdf"/> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:49:17Z</dcterms:available> <dc:contributor>Kroha, Johann</dc:contributor> <dcterms:title>Nonequilibrium Josephson oscillations in Bose-Einstein condensates without dissipation</dcterms:title> <dc:contributor>Posazhennikova, Anna</dc:contributor> <dcterms:bibliographicCitation>First publ. in: arXiv:0903.5459v4 [cond-mat.quant-gas] 2009; also publ. in: Physical Review Letters 103 (2009), 10, 105302</dcterms:bibliographicCitation> <dc:format>application/pdf</dc:format> <dcterms:rights rdf:resource="https://kops.uni-konstanz.de/page/termsofuse"/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> </rdf:Description> </rdf:RDF>
