This emphasizes a connection between stress-imposed deformation of soft and hard matter, in particular, colloidal and metallic systems. A generalized Maxwell model rationalizes logarithmic creep for long times and low stresses. We identify diverging time scales approaching a critical yield stress. At intermediate times, strong aging effects are seen, which we link to a stress overshoot seen in stress-strain curves.</dcterms:abstract> <dcterms:rights rdf:resource=""/> <dcterms:available rdf:datatype="">2012-06-20T13:09:41Z</dcterms:available> <dc:contributor>Voigtmann, Thomas</dc:contributor> <dc:contributor>Siebenbürger, Miriam</dc:contributor> <dcterms:bibliographicCitation>Publ. in: Physical Review Letters ; 108 (2012), 25. - 255701</dcterms:bibliographicCitation> <dc:language>eng</dc:language> <dc:contributor>Ballauff, Matthias</dc:contributor> <dc:creator>Ballauff, Matthias</dc:creator> <dc:rights>deposit-license</dc:rights> <dc:date rdf:datatype="">2012-06-20T13:09:41Z</dc:date> <dcterms:issued>2012</dcterms:issued> <bibo:uri rdf:resource=""/> <dc:creator>Siebenbürger, Miriam</dc:creator> <dcterms:title>Creep in colloidal glasses</dcterms:title> <dc:creator>Voigtmann, Thomas</dc:creator> </rdf:Description> </rdf:RDF>
