    • Coherence-induced entanglement 

      Li, F. L.; Xiong, H.; Zubairy, M. Suhail (American Physical Society, 2005)
      We show how atomic coherence can lead to entanglement between two thermal fields at a temperature T. We first show that the passage of a three-level atom in V configuration without coherence cannot create entanglement. ...
    • Condensation of N bosons. II. Nonequilibrium analysis of an ideal Bose gas and the laser phase-transition analogy 

      Kocharovsky, VV; Scully, Marlan O.; Zhu, S. Y.; Zubairy, M. Suhail (American Physical Society, 2000)
      A nonequilibrium approach to the dynamics and statistics of the condensate of an ideal N-atom Bose gas cooling via interaction with a thermal reservoir using the canonical ensemble is developed. We derive simple analytical ...
    • Control of the Goos-Hanchen shift of a light beam via a coherent driving field RID A-4660-2010 

      Wang, Li-Gang; Ikram, Manzoor; Zubairy, M. Suhail (American Physical Society, 2008)
      We present a proposal to manipulate the Goos-Hanchen shift of a light beam via a coherent control field, which is injected into a cavity configuration containing the two-level atomic medium. It is found that the lateral ...
    • Control of the Lamb shift by a driving field 

      Yang, Shuai; Zheng, Hang; Hong, Ran; Zhu, Shi-Yao; Zubairy, M. Suhail (American Physical Society, 2010)
      A unitary transformation approach is used to study the energy level shift of the atom coupled to both a vacuum electromagnetic field and a driving laser. The Lamb shift of the energy levels is shown to depend on the Rabi ...
    • Electromagnetically induced transparency in rubidium vapor prepared by a comb of short optical pulses 

      Sautenkov, V. A.; Rostovtsev, Y. V.; Ye, C. Y.; Welch, George R.; Kocharovskaya, O.; Scully, Marlan O. (American Physical Society, 2005)
      It was shown by Kocharovskaya and Khanin [Sov. Phys. JETP 63, 945 (1986)] that a comb of optical pulses can induce a ground-state atomic coherence and change the optical response of an atomic medium. In our experiment, we ...
    • Enhancement of magneto-optic effects via large atomic coherence in optically dense media RID B-9041-2008 

      Sautenkov, V. A.; Lukin, M. D.; Bednar, CJ; Novikova, I.; Mikhailov, E.; Fleischhauer, M.; Velichansky, V. L.; Welch, George R.; Scully, Marlan O. (American Physical Society, 2000)
      We utilize the generation of large atomic coherence in optically dense media to enhance the resonant nonlinear magneto-optic effect by several orders of magnitude, thereby eliminating power broadening and improving the ...
    • Fast noise in the Landau-Zener theory RID B-5617-2009 

      Pokrovsky, Valery L.; Sinitsyn, NA. (American Physical Society, 2003)
      We study the influence of a fast noise on Landau-Zener transitions. We demonstrate that a fast colored noise much weaker than the conventional white noise can produce transitions itself or can change substantially the ...
    • Manipulation of the Raman process via incoherent pump, tunable intensity, and phase control 

      Wang, Li-Gang; Qamar, Sajid; Zhu, Shi-Yao; Zubairy, M. Suhail (American Physical Society, 2008)
      We present a proposal to manipulate the Raman process via incoherent pump, tunable intensity, and phase control of the driving fields. It is found that Raman absorptive peaks can become Raman gain peaks by controlling the ...
    • Nonlinear magneto-optical rotation of elliptically polarized light RID A-1272-2007 RID B-9041-2008 

      Matsko, A. B.; Novikova, I.; Zubairy, M. Suhail; Welch, George R. (American Physical Society, 2003)
      We predict theoretically and demonstrate experimentally an ellipticity-dependent nonlinear magneto-optic rotation of elliptically polarized light propagating in a medium with atomic coherence. We show that this effect ...
    • Quantum disentanglement eraser: A cavity QED implementation 

      Zubairy, M. Suhail; Agarwal, G.S.; Scully, Marlan O. (American Physical Society, 2004)
      A possible experimental scheme of the Garisto-Hardy disentanglement eraser based on a cavity QED system is presented. This scheme can be used for a delayed choice quantum eraser. It also allows us to acquire single-qubit ...
    • Spectral narrowing via quantum coherence 

      Mikhailov, Eugeniy E.; Sautenkov, Vladimir A.; Rostovtsev, Yuri V.; Zhang, Aihua; Zubairy, M. Suhail; Scully, Marlan O.; Welch, George R. (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 ...
    • 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 ...
    • Vacuum squeezing in atomic media via self-rotation RID A-1272-2007 RID B-9041-2008 

      Matsko, A. B.; Novikova, I.; Welch, George R.; Budker, D.; Kimball, D. F.; Rochester, S. M. (American Physical Society, 2002)
      When linearly polarized light propagates through a medium in which elliptically polarized light would undergo self-rotation, squeezed vacuum can appear in the orthogonal polarization. A simple relationship between self-rotation ...
