依赖时间和强度耦合J-C模型中光场的聚束与反聚束效应

Bunching and antibunching effects of light field in time-dependent and intensity-dependent coupling J-C model

研究了依赖于时间和强度耦合J-C模型.并讨论了原子与光场的耦合受到高斯型时间脉冲限制时,脉冲宽度和光场强度对光场聚束与反聚束效应的影响.结果表明,在此模型下可以通过改变脉冲宽度有效地控制光场的聚束或反聚束程度.

The effects of bunching and antibunching of light field in the time-dependent and intensity-dependent J-C model are investigated.The effect of different pulse widths and light field intensity on bunching and antibunching effects of light field is discussed when the coupling of atom and light field is time-dependent.The results show that the time-evolution of second-order correlation function in this model is different from other intensity-dependent models,and that we can control the degree of bunching and antibunching effectively by controling the pulse width.
