collapse and revival meaning in English

坍缩恢复现象

Collapse and revival phenomena of a two - level atom in odd and even coherent states
奇偶相干态中二能级原子的动力学行为
It has been shown that whether resonant or non - resonant interaction system , the kerr effect weakens the coupling of the field - atom , shortens the cycle of quantum collapses and revivals of the atomic level occupation and makes the nonclassical correlation properties steady . kerr effects on the properties of the correlation , on the correlation intensity between the two - mode , on the photon - number distribution and on the bunching or antibunching effect of the two - mode su ( 1 , 1 ) coherent states produce obviously different characters when it is changed the initial intensity of the light field . that is to say , kerr effect on the two interaction systems is accorded
数值计算结果表明：无论是共振还是非共振相互作用， kerr效应均使原子与光场的耦合减弱，原子布居的崩塌与复苏的周期缩短，光场的非经典相关的稳定性增强；在初始光场较弱和较强两种情况下，类kerr介质对双模su ( 1 ， 1 )相干态场两模间的相关性、相关程度以及光子的聚束与反聚束效应产生的作用均有明显的区别，即kerr效应对系统在共振及非共振作用时的影响是一致的。
