Spectral narrowing via quantum coherence
(American Physical Society, 2006)
We have studied the transmission through an optically thick Rb-87 vapor that is illuminated by monochromatic and noise-broadened laser fields in Lambda configuration. The spectral width of the beat signal between the two ...
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 ...
Quantum electrodynamics of accelerated atoms in free space and in cavities
(American Physical Society, 2006)
We consider a gedanken experiment with a beam of atoms in their ground state that are accelerated through a single-mode cavity. We show that taking into account of the "counterrotating" terms in the interaction Hamiltonian ...
