| 摘 要： | 根据辐射的量子统计理论,讨论了理想非简并双光子Jaynes-Cummings模型的原子算子动力学行为,发现了原子布居数反转在时间演化过程中Rabi振荡的量子塌陷与复苏现象。该现象的窄波包形式、低对称性及短周期,是低简并度多光子转变条件下原子与辐射场作用的突出特征。

| Abstract: | The dynamical properties of the atomic operators in a nondegenerate two-photon Jaynes-Cummings model is discussed from the quantum statistical theory of radialion, which reveals the phenomenon of quantum revival and collopse in Rabi oscillation of the atomic population inversion and confirms that the narrowforrn, lower symmetry and short period of the wave packet of the phenomenon are the outstanding features resulting from the interaction between the atom and the radiation field with a lower degenerate multiphoton process. |
