Atom microscopy via two-photon spontaneous emission spectroscopy RID A-5077-2009
(American Physical Society, 2009)
We study subwavelength position measurement via spontaneous emission spectroscopy with two photons. Our model systems are a single Lambda-type three-level atom, in which a dual interaction generates two independent photons, ...
Localization of atomic ensembles via superfluorescence RID B-9093-2009 RID A-5077-2009
(American Physical Society, 2007)
The subwavelength localization of an ensemble of atoms concentrated to a small volume in space is investigated. The localization relies on the interaction of the ensemble with a standing wave laser field. The light scattered ...
Measurement of the separation between atoms beyond diffraction limit RID A-5077-2009
(American Physical Society, 2006)
Precision measurement of small separations between two atoms or molecules has been of interest since the early days of science. Here, we discuss a scheme which yields spatial information on a system of two identical atoms ...
Atom localization and center-of-mass wave-function determination via multiple simultaneous quadrature measurements RID A-5077-2009
(American Physical Society, 2007)
We discuss localization and center-of-mass wave-function measurement of a quantum particle using multiple simultaneous dispersive interactions of the particle with different standing-wave fields. In particular, we consider ...
Distilling two-atom distance information from intensity-intensity correlation functions RID A-5077-2009
(American Physical Society, 2006)
The intensity-intensity correlation function of the resonance fluorescence light of two two-level atoms driven by a resonant standing-wave laser field is examined. Our aim is to gain information on the distance between the ...
