| 摘 要： | 研究了存在相位退相干的两能级原子与相干态光场相互作用系统，通过求解主方程得到了原子反转算符期待值和光子数分布随时间演化的表达式，讨论了相位退相干系数对原子和光场非经典特性的影响,研究表明：相位退相干系数对原子反转算符时间演化的崩塌和回复效应、光场光子数分布振荡和反聚束效应有十分显著的影响．

| Abstract: | The time evolution of the collapses and revivals of the atomic inversion and the photon number distribution in a system where a two-level atom interacts with the field that is prepared in the coherent state and discussed the influence of the phase decoherence on nonclassical effects are studied. It is shown that the phase decoherence coefficient has notable influence on the collapses and revivals of the atomic inversion, the photon number distribution and photon antibunching. |
