利用全量子理论,研究了单模光场与二能级原子相互作用系统的量子场熵演化规律.利用MATLAB进行数值计算,讨论了光场的平均光子数、光场-原子之间的耦合系数g对量子场熵演化规律的影响,得到了相应的结论.

The quantum field entropy evolution of Single-mode light field interacting with two -level atom is restudied by means of the full quantum theory. Using MATLAB to carry on numerical calculation,the influence of the initial mean photon number 〈n〉, the couple intensity g and the excited field intensity on the quantum field entropy evolution is invest...
