    • Functional Keldysh theory of spin torques 
      Duine, R. A.; Nunez, A. S.; Sinova, Jairo; MacDonald, A. H. (American Physical Society, 2007)
      We present a microscopic treatment of current-induced torques and thermal fluctuations in itinerant ferromagnets based on a functional formulation of the Keldysh formalism. We find that the nonequilibrium magnetization ...
    • Hanbury Brown-Twiss effect and thermal light ghost imaging: A unified approach 
      Wang, Li-Gang; Qamar, Sajid; Zhu, Shi-Yao; Zubairy, M. Suhail (American Physical Society, 2009)
      We compare the Hanbury Brown-Twiss (HBT) and the thermal light ghost imaging schemes in both near and far fields. Both effects arise as a result of the intensity fluctuations of the thermal light and we find that the ...
    • 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 ...
