    • 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 ...
    • Effect of the counterrotating-wave terms on the spontaneous emission from a multilevel atom 
      Li, Zheng-Hong; Wang, Da-Wei; Zheng, Hang; Zhu, Shi-Yao; Zubairy, M. Suhail (American Physical Society, 2009)
      The spontaneous decay of a multilevel atom interacting with the electromagnetic field in free space is investigated with a unitary transformation method, which is introduced in order to include all rotating and counter-rotating ...
