    • Quenching of spontaneous emission through interference of incoherent pump processes 

      Kapale, KT; Scully, Marlan O.; Zhu, S. Y.; Zubairy, M. Suhail (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 ...
    • Spectroscopic measurement of an atomic wave function 

      Kapale, KT; Qamar, S.; Zubairy, M. Suhail. (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 ...
    • Subwavelength atom localization via amplitude and phase control of the absorption spectrum 

      Sahrai, M.; Tajalli, H.; Kapale, KT; Zubairy, M. Suhail. (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 

      Kapale, KT; Zubairy, M. Suhail. (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 

      Sahrai, M.; Tajalli, H.; Kapale, KT; Zubairy, M. Suhail (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 ...
