Such systems are useful models for the study of monolayers on a substrate. We find that the interaction with a substrate potential completely changes the miscibility of a binary, hard disc mixture at low external field amplitudes. The underlying ordering mechanisms leading to this laser-induced de-mixing differ, depending on which components interact with the substrate potential. Generic effects of confinement on crystalline order in two dimensions are studied in a model system of point particles interacting via a potential proportional to r(-12). The state of the system (a strip of width D) depends very sensitively on the precise boundary conditions at the two confining walls. Commensurate, corrugated boundary conditions enhance both orientational order and positional order. In contrast, smooth repulsive boundaries enhance only the orientational order and destroy positional (quasi-) long range order. As external fields have a strong impact on the elastic behaviour of colloidal crystals there is a need to analyse the elastic response in such systems for the field-free case first. To this aim we study the strain-strain correlation functions in a two-dimensional crystal formed by super-paramagnetic colloids, as monitored by standard video microscopy.</dcterms:abstract> <dc:contributor>Keim, Peter</dc:contributor> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:language>eng</dc:language> <dc:creator>Keim, Peter</dc:creator> <dc:creator>Maret, Georg</dc:creator> <dc:creator>Nielaba, Peter</dc:creator> <dc:contributor>Ricci, Andrea</dc:contributor> <dc:creator>Sengupta, Surajit</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/903"/> <dcterms:bibliographicCitation>Publ. in: Journal of Physics: Condensed Matter 20 (2008), 404218</dcterms:bibliographicCitation> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/903/1/Franzrahe_opus-120744.pdf"/> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dcterms:title>Field-induced ordering phenomena and non-local elastic compliance in two-dimensional colloidal crystals</dcterms:title> <dc:contributor>Sengupta, Surajit</dc:contributor> <dcterms:issued>2008</dcterms:issued> </rdf:Description> </rdf:RDF>
