The average equilibration current through the optical lattice, for strong latticereservoir coupling and finite temperatures, is calculated within the Landauer formalism using a nonequilibrium Green’s functions approach. We moreover determine quantum and thermal fluctuations in the transport and find significant shot-to-shot deviations from the average equilibration current. We show how to control the atomic current by engineering specific optical lattice potentials without requiring site-by-site manipulations and suggest the realization of a single level model. Based on this model we discuss the blocking effect on the atomic current resulting from weak interactions between the fermions.</dcterms:abstract> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:contributor>Bruderer, Martin</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2012-01-30T12:18:01Z</dc:date> <dc:language>eng</dc:language> <dc:rights>terms-of-use</dc:rights> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/16153/1/Belzig.pdf"/> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/16153"/> <dc:contributor>Belzig, Wolfgang</dc:contributor> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/16153/1/Belzig.pdf"/> <dcterms:issued>2012</dcterms:issued> <dc:creator>Belzig, Wolfgang</dc:creator> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dcterms:title>Mesoscopic transport of fermions through an engineered optical lattice connecting two reservoirs</dcterms:title> <dc:creator>Bruderer, Martin</dc:creator> <dcterms:bibliographicCitation>First publ. in: Physical Review A ; 85 (2012), 1. - 013623</dcterms:bibliographicCitation> </rdf:Description> </rdf:RDF>
