Abstract

The dynamics of the driven Jaynes-Cummings model where a two-level atom iscoupled to a single mode of cavity fields and is driven by an external coherent held is investigated. We find that in this model quantum collapse andrevivals of the atomic population inversion and squeezing of the cavity field can be generated from a thermal photon state. We also notice that the squeezing is very sensitive to the mean number of thermal photons initially in the cavity, but the quantum collapse and revivals are not. The influenceof the amplitude of the driving field and various detuning parameters on the nonclassical effects is discussed. The result shows that one can use theexternal field to control nonclassical effects in the Jaynes-Cummings model.
