Abstract
The Milburn equation is solved exactly for multi-quanta Jaynes-Cummings model (JCM) in the presence of Stark shift. The influence of intrinsic decoherence and Stark shift on nonclassical properties (such as collapses and revivals of the population inversion and squeezing of the field modes) of the system is studied. The dynamical behaviour is adjusted in the presence of Stark shift. It is shown that the dynamic Stark shift plays an important role in nonclassical effects in multi-quanta processes. Also, even in the presence of Stark shift the revivals of the population inversion and squeezing of the field are destroyed in the decoherence process.
