Field Entropy Evolution of the Interaction Between Three-level Cascade Atom and Light Field Without Rotating Wave Approximation
In this paper, the field entropy evolution in the system of three-level cascade atom interacting with a single mode light field is studied by means of the quantum theory without rotating wave approximation. Compared with the result of rotating wave approximation, the influence of the virtual photon field and of the initial mean photon number on the evolution of field entropy is also discussed.
