Analyzing these data within a schematic model of the mode-coupling theory for dense glass formers under shear, values for the critical dynamic yield stress (the stress resulting in the limit of arbitrarily slow shear, at the glass transition) are estimated. We discuss two possible scenarios, that of a continuous rise in the dynamic yield stress at the transition, and that of a discontinuous transition, and discuss the data range that needs to be covered to decide between the two cases. A connection is made to the two commonly drawn versions of the jamming diagram, one convex and one concave regarding to the shape of the solid region.</dcterms:abstract> <dc:contributor>Voigtmann, Thomas</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/16596"/> <dc:language>eng</dc:language> <dc:rights>deposit-license</dc:rights> <dcterms:issued>2011-09</dcterms:issued> <dcterms:bibliographicCitation>Publ. in: The European Physical Journal E : Soft Matter and Biological Physics ; 34 (2011), 9. - 106</dcterms:bibliographicCitation> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-11-07T07:24:13Z</dcterms:available> </rdf:Description> </rdf:RDF>
