We show that the electron-hole pairs can be generated in a controlled way using harmonic and biharmonic time-dependent voltages applied to a quantum contact, and we obtain the probabilities of the pair creations. For a biharmonic voltage drive, we find that the probability of a pair creation decreases in the presence of an in-phase second harmonic. This accounts for the suppression of the excess noise observed experimentally (Gabelli and Reulet, arXiv:1205.3638), proving that dynamic control and detection of elementary excitations in quantum conductors are within the reach of the present technology.</dcterms:abstract> <dc:creator>Belzig, Wolfgang</dc:creator> <dcterms:bibliographicCitation>Physical Review B ; 86 (2012), 24. - 241306</dcterms:bibliographicCitation> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/22482"/> <dc:contributor>Belzig, Wolfgang</dc:contributor> <dc:language>eng</dc:language> </rdf:Description> </rdf:RDF>
