A combination of molecular dynamics simulation, mode-coupling theory and confocal microscopy experiments is used to investigate the origins of the widely observed stress overshoot and (previously not reported) super-diffusive motion in the transient dynamics. A link between the macro-rheological stress versus strain curves and the microscopic particle motion is established. Negative correlations in the transient auto-correlation function of the potential stresses are found responsible for both phenomena, and arise even for homogeneous flows and almost Gaussian particle displacements.</dcterms:abstract> <dc:creator>Egelhaaf, Stefan Ulrich</dc:creator> <dcterms:title>From equilibrium to steady state : the transient dynamics of colloidal liquids under shear</dcterms:title> <dc:creator>Brader, Joseph M.</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/4684"/> <dc:contributor>Egelhaaf, Stefan Ulrich</dc:contributor> <dc:contributor>Horbach, Jürgen</dc:contributor> <dc:creator>Zausch, Jochen</dc:creator> <dc:contributor>Voigtmann, Thomas</dc:contributor> <dc:format>application/pdf</dc:format> <dc:creator>Laurati, Marco</dc:creator> <dc:contributor>Zausch, Jochen</dc:contributor> <dc:creator>Horbach, Jürgen</dc:creator> <dc:rights>deposit-license</dc:rights> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:49:33Z</dcterms:available> <dc:contributor>Laurati, Marco</dc:contributor> <dc:language>eng</dc:language> <dc:contributor>Brader, Joseph M.</dc:contributor> <dc:creator>Fuchs, Matthias</dc:creator> <dcterms:bibliographicCitation>First publ. in: Journal of Physics : Condensed Matter ; 20 (2008). - 404210</dcterms:bibliographicCitation> <dc:contributor>Fuchs, Matthias</dc:contributor> <dcterms:issued>2008</dcterms:issued> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:49:33Z</dc:date> </rdf:Description> </rdf:RDF>
