    • 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 ...
    • Entanglement of Gaussian states using a beam splitter RID A-4660-2010 RID B-8901-2008 

      Tahira, Rabia; Ikram, Manzoor; Nha, Hyunchul; Zubairy, M. Suhail (American Physical Society, 2009)
      We study an experimental scheme to generate Gaussian two-mode entangled states via beam splitter. Specifically, we consider a nonclassical Gaussian state (squeezed state) and a thermal state as two input modes, and evaluate ...
    • Landau-Zener transitions in a linear chain 

      Pokrovsky, Valery L.; Sinitsyn, NA. (American Physical Society, 2002)
      We present an exact asymptotic solution for electron transition amplitudes in an infinite linear chain driven by an external time-dependent electric field. This solution extends the Landau-Zener theory for the case of an ...
    • Multiphase transport model for relativistic heavy ion collisions 

      Lin, ZW; Ko, Che Ming; Li, Ba; Zhang, B.; Pal, S. (American Physical Society, 2005)
      We describe in detail how the different components of a multiphase transport (AMPT) model that uses the heavy ion jet interaction generator (HIJING) for generating the initial conditions, Zhang's parton cascade (ZPC) for ...
    • Nonlinear magneto-optic polarization rotation with intense laser fields 

      Hsu, Paul S.; Patnaik, Anil K.; Welch, George R. (American Physical Society, 2008)
      We have studied the nonlinear Faraday effect with intense linear polarized light in an optically thick atomic rubidium vapor. We demonstrate that the polarization rotation rate (rotation angle per unit magnetic field, in ...
    • 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 ...
    • Proposal for direct measurement of concurrence via visibility in a cavity QED system 

      Lee, Sang Min; Ji, Se-Wan; Lee, Hai-Woong; Zubairy, M. Suhail (American Physical Society, 2008)
      An experimental scheme is proposed that allows direct measurement of the concurrence of a two-qubit cavity system. It is based on the cavity-QED technology using atoms as flying qubits and relies on the identity of the ...
    • 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 ...
    • Two-mode single-atom laser as a source of entangled light RID A-5077-2009 

      Kiffner, M.; Zubairy, M. Suhail; Evers, J.; Keitel, C. H. (American Physical Society, 2007)
      A two-mode single-atom laser is considered, with the aim of generating entanglement in macroscopic light. Two transitions in the four-level gain medium atom independently interact with the two cavity modes, while two other ...
    • 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 ...
