Influence of initial atomic coherence on squeezing of radiative field in the two-photon Jaynes-Cummings model |
| |
| Abstract: | In this paper, the general evolution laws of the two-photon Jaynes-Cummings model with initially arbitrary states have been investigated. And the emphasis is put on the influenec of the initial atomic coherence on the squeezing of radiative field in the two-photon Jaynes-Oummings model. As an example, the squeezing of the field in the interaction of a two-level atom of arbitrary initial states with the vacuum and coherent field is studied, and the squeezing of the field under various conditions has been calculated numerically. |
