Abstract
The work presents some aspects of studying the two-level atom in a Kerr media interacting with a single-mode electromagnetic field, which is the superposition of squeezed displaced Fock states. We discuss the effect of the new field on quantum entropy and the entanglement of the atom-field system in the two-photon process. The exact results are employed to perform a careful investigation of the temporal entropy evolution. The position and momentum entropy squeezing of the optical field are investigated. The general conclusions obtained are illustrated by numerical results.
