By making use of fundamental concepts from quantum field theory on spacetime metrics, the nonlinear interaction behind the electro-optic effect can be reformulated in terms of an Unruh-DeWitt detector coupled to a conjugate field during a very short time interval. When the coupling lasts for a time interval comparable to the oscillation periods of the detected field mode (i.e. the subcycle regime), virtual particles inhabiting the field vacuum are transferred to the detector in the form of real excitations. We demonstrate that this behavior can be rigorously translated to the scenario of electro-optic sampling of the quantum vacuum, in which the (spectrally filtered) probe works as an Unruh-DeWitt detector, with its interaction-generated photons arising from virtual particles inhabiting the electromagnetic vacuum. We discuss the specific working regime of such processes, and the consequences through characterization of the quantum light involved in the detection.</dcterms:abstract> <dcterms:title>Realizing an Unruh-DeWitt detector through electro-optic sampling of the electromagnetic vacuum</dcterms:title> <dc:creator>Leitenstorfer, Alfred</dc:creator> <dc:language>eng</dc:language> <dc:creator>Moskalenko, Andrey S.</dc:creator> <dc:contributor>Burkard, Guido</dc:contributor> <dc:contributor>Ralph, Timothy C.</dc:contributor> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/53597"/> </rdf:Description> </rdf:RDF>
