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 ...
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 ...
