| 9. | It has been shown that : with the increase of the kerr medium intensity parameter u , the rabi oscillation extent of the mean photon number decrease and the rabi oscillation frequency becomes rapid , the antibunching effect becomes strengthened ; with the increase of n , the interaction between the field and atoms gradually becomes weak , however , the interaction between the field and the kerr medium gradually becomes strengthened and happen in advance ; with the increase of the coupling constants of two atoms , the rabi oscillation extent of the mean photon number decrease and the rabi oscillation frequency becomes rapid too , the antibunching effect becomes weak 结果表明:随着值的增加,光子统计演化曲线的rabi振荡的幅度减小,振荡频率变快,系统的反聚束效应增强;随着初始场强( ? )的增大,场与原子的相互作用逐渐减弱,而与介质的相互作用逐渐加强并提前发生。随着原子间耦合系数g的增大,光子统计演化曲线的rabi振荡的幅度减小且振荡周期缩短,同时,系统的反聚束效应减弱。 |
