摘要
研究了存在偶极-偶极相互作用的两个等同二能级原子与单模光场喇曼耦合过程的腔场谱.结果表明,当两原子处于同一能级时,腔场谱在弱场和强场条件下相应地为五峰和三峰结构.当两原子初态处于不同能级时,交换对称性对谱结构有明显的影响. 原子间的相互作用只在初始场很弱时才会影响谱结构.
Abstract
The cavity field spectrum of two coupled atoms Raman interacting with a simgle mode field in an ideal cavity is investigated. The effects of dipole dipole interaction of atoms and exchange symmetry of the initial state of atoms on the cavity field spectra are analyzed. It is found that five peak structure appears for weak fields, and three peak structure appears for strong field. When the two atoms are in the different state initially, the exchange symmetry of the atoms play a decisive role in the structure of the cavity field spectra.
