(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, ...
-
(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 ...
-
(American Physical Society, 2000)Based on an extended Hubbard model, we present calculations of both the local (i.e., single-site) and spatially averaged differential tunneling conductance in d-wave superconductors containing nonmagnetic impurities in the ...
-
(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 ...
-
(American Physical Society, 2008)We study the possibility of creating spatial patterns having subwavelength size by using the so-called dark states formed by the interaction between atoms and optical fields. These optical fields have a specified spatial ...
-
(American Physical Society, 2000)The quasiparticle resonant states around a single nonmagnetic impurity with unitary scattering in a d-wave superconductor is studied by solving the Bogoliubov-de Gennes equations based on a t-J model. Both the spatial ...
