Nonclassical effects for a qubit coupled to a coherent two-mode cavity with intrinsic decoherence
In this paper, we use the su(1,1)-algebraic treatment to explore the effects of the intrinsic decoherence in a two-mode cavity containing a two-level atom.Each field is resonant with the qubit through a four-photon process.The role of the intrinsic decoherence and chainsaw file the superposition of the initial generalized Barut-Girardello coherent
