Numerous modes that appear below Tc show pronounced T dependences of their amplitudes, frequencies, and dampings. Utilizing the time-dependent Ginzburg-Landau theory we show that these modes result from linear coupling of the electronic part of the order parameter to the 2kF phonons, while the (electronic) CDW amplitude mode is overdamped.</dcterms:abstract> <dc:contributor>Beyer, Markus</dc:contributor> <dc:creator>Bilijakovic, Katica</dc:creator> <dc:contributor>Kabanov, Viktor V.</dc:contributor> <dc:creator>Beyer, Markus</dc:creator> <dc:language>eng</dc:language> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:56:15Z</dcterms:available> <dc:contributor>Schaefer, Hanjo</dc:contributor> <dc:format>application/pdf</dc:format> <dc:creator>Kabanov, Viktor V.</dc:creator> <dc:rights>deposit-license</dc:rights> <dc:contributor>Demsar, Jure</dc:contributor> <dcterms:bibliographicCitation>First publ. in: Physical Review Letters 105 (2010), 066402 + Suppl. material</dcterms:bibliographicCitation> <dcterms:title>Disentanglement of the Electronic and Lattice Parts of the Order Parameter in a 1D Charge Density Wave System Probed by Femtosecond Spectroscopy</dcterms:title> <dc:creator>Schaefer, Hanjo</dc:creator> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dcterms:issued>2010</dcterms:issued> </rdf:Description> </rdf:RDF>
