双原子与单模腔场Raman相互作用过程中原子与场的动力学特性

DYNAMICAL PROPERTIES OF THE ATOMS AND THE FIELD IN THE RAMAN INTERACTION OF TWO ATOMS WITH A SINGLE-MODE CAVITY FIELD

用解析方法研究了双原子与单模腔场的共振Raman相互作用过程中,双原子与腔场之间耦合常数的相对大小对原子与场的动力学特性的影响.在一般情况下,Rabi振荡出现四个不同的崩溃与回复系列,位相概率分布呈现四峰结构.对于不同的原子初态,Rabi振荡的崩溃与回复、原子与场的纯态演化以及场的位相特性有很大差异.

By analytical method, we study the effect of the relative value of two atom-field coupling constants and also that of the initial atomic states on the dynamical properties of the atoms and the field in the Raman interaction of two two-level atoms with a single-mode radiation field. The results show that there are four col-lapserevival series in the atomic Rabi oscillation and four peaks in the phase probability distribution in general.
