    • 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. ...
    • 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 ...
    • Disentanglement in a two-qubit system subjected to dissipation environments RID A-4660-2010 
      Ikram, Manzoor; Li, Fu-li; Zubairy, M. Suhail (American Physical Society, 2007)
      We investigate the time evolution of entanglement of various entangled states of a two-qubit system exposed to either thermal or squeezed reservoirs. We show that, except for the vacuum reservoir, the sudden-death of ...
    • One-atom correlated-emission laser RID C-6638-2008 
      Kim, Ho-Joon; Khosa, Ashfaq H.; Lee, Hai-Woong; Zubairy, M. Suhail (American Physical Society, 2008)
      We study a four-level double-Lambda atomic configuration working as a two photon linear amplifier where two atomic transitions independently interact with cavity mode, while the other transitions are driven by a strong ...
    • 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 ...
