摘要：
The influence of atomic coherence on collapse and revival phenomenon in the k-photon Jaynes-Cummings model was investigated. The system considered in this study is a two-level atom interacting with a single-mode quantized field via the k-photon transition mechanism. The mathematical expression for the atomic inversion was derived. The equation is suitable for the general case. It is shown that the atomic inversion depends on not only the statistics of the field, but also the phases of the field and atom. The numerical calculation results were obtained and discussed. It is concluded that the collapse and revival behavior of the atomic inversion does not drastically depend on the initial coherence of the atom, but this coherence evidently influences the amplitude of the oscillations.

摘要：
Jaynes-Cummings model (JCM) for describing a two-level atom interacting with a single-mode radiation field via the one-photon transition is one of the important theoretical models in quantum optics. Recently, Sukumar et al. have generalized the JCM to

Ⅰ. INTRODUCTION The squeezed field state, which exhibits fluctuations in one quadrature component of field smaller than those associated with the vacuum state, at the cost of increased fluctuations in the other quadrature component, is one type of the pure quantum-mechanical states of the radiation field. The state has been extensively studied because of its potential applications in optical communications and weak signal detections since it was introduced by Stoler in 1970.
