摘要：

The effects of the atomic motion and of the field-mode structure, on the evolution of the field entropy and the production of the Schrodinger-cat state are examined in the Jaynes-Cummings model. The results show that the atomic motion and the field-mode structure play an important role in the evolution of the field entropy and the generation of the Schrodinger-cat state and some new conclusions can be obtained.
