    • Continuous-variable entanglement in a correlated spontaneous emission laser 
      Tan, HT; Zhu, S. Y.; Zubairy, M. Suhail (American Physical Society, 2005)
      We discuss the generation and evolution of entangled light in a correlated spontaneous emission laser. The master equation for the two-mode field in a cavity is derived and solved analytically. The time-dependent characteristic ...
    • Improving engine efficiency by extracting laser energy from hot exhaust gas RID A-1272-2007 
      Rostovtsev, Y. V.; Matsko, A. B.; Nayak, N.; Zubairy, M. Suhail; Scully, Marlan O. (American Physical Society, 2003)
      We show that it is possible to improve the efficiency of a classical Otto-cycle heat engine by adding a high-Q microwave cavity and a laser system that can extract coherent laser energy from thermally excited "exhaust" ...
    • Inversionless lasing with self-generated driving field 
      Belyanin, Alexey; Bentley, C.; Capasso, F.; Kocharovskaya, O.; Scully, Marlan O. (American Physical Society, 2001)
      We propose and study resonant ladder schemes of inversionless lasing on a fast-decaying transition when the population inversion is not possible or Very difficult to achieve. The driving field on a neighboring, slowly ...
    • 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 ...
    • 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 ...
