研究了非旋波近似下Jaynes-Cummings(J-C)模型中的场熵演化规律,并与旋波近似下的相应结果进行比较,讨论了虚光子过程对场熵演化的影响。The evolution law of the field entropy in the J-C model without rotating-wav approximation are invesitigated. Comparing with the results obtained with the rotating-wave approximation, the influence of the virtual photon processes on the evolution of the field entropy are discussed.
