双原子非简并拉曼过程中原子与腔场的动力学

Atomic and Field Dynamics in Two-atom Nondegenerate Raman Process

本文研究两原子与双模量子腔场的拉曼相互作用，分析原子反转度和腔场平均光子数的时间演化，考察腔场初态、初场强度以及原子间偶极相互作用的影响，并与单原子情况进行了比较，得到了一些新的有意义的结果。

The atomic and field dynamics in the Raman interaction of two atoms with twomodes of a quantum cavity field were studied. The analytical expressions for the timeevolutions of the atomic inversion and of the mean photon number were presented. Theeffects of the initial field states, the initial field intensities, and the dipole-dipole couplingof atoms were examined. By comparing them with tile results in one-atom case, we foundsome new and interesting results.
