研究对相干态与级联三能原子相互作用的动力学特性。结果表明,无论场模与原子的中间能级是否失谐,拉比振荡和互关联函数的时间演化都呈现崩溃与回复现象,但崩溃的持续时间随失谐量的增加而迅速延长,且两模之间随时间的演化既出现关联也出现反关联。

The dynamical properties of a three level cascade atom interacting with pair coherent state are studied. Both Rabi oscillation and the time evolution of the cross correlation function show collapse and revival phenomena whether the individual field modes are detuned from the intermediate atomic level or not, but the times of collapses increase quickly with increasing the detuning amount. We also observed that the modes of pair coherent state show both correlation and anticorrelation depending on the time of observation.
