Spectroscopic measurement of an atomic wave function
(American Physical Society, 2003)
We present a simple spectroscopic method based on Autler-Townes spectroscopy to determine the center-of-mass atomic wave function. The detection of spontaneously emitted photons from a three-level atom, in which two upper ...
Quenching of spontaneous emission through interference of incoherent pump processes
(American Physical Society, 2003)
We investigate the steady-state spontaneous emission of a V-type three-level atom, with the coherence between the two upper levels modified and controlled via incoherent pumping to a fourth auxiliary level. The external ...
Subwavelength atom localization via amplitude and phase control of the absorption spectrum
(American Physical Society, 2005)
We propose a scheme for subwavelength localization of an atom conditioned upon the absorption of a weak probe field at a particular frequency. Manipulating atom-field interaction on a certain transition by applying drive ...
Subwavelength atom localization via amplitude and phase control of the absorption spectrum. II
(American Physical Society, 2006)
Interaction of the internal states of an atom with spatially dependent standing-wave cavity field can impart position information of the atom passing through it leading to subwavelength atom localization. We recently ...
Tunable phase control for subluminal to superluminal light propagation
(American Physical Society, 2004)
We demonstrate tunable control of the group velocity of a weak probe pulse from subluminal to superluminal. The model is an extended Lambda-type system with two extra control fields and an extra energy level. Phase variation ...
