单模辐射场与N个原子相互作用理论

THEORY OF INTERACTION OF A SINGLE-MODE RADIATION FIELD WITH N ATOMS

本文用玻色算符的三维型哈密顿量描述单模辐射场与N个两能级原子的相互作用。当模1很强,即处于高能级的原子数目很大时,得到了作用系统的动力学变化规律。

The interaction of a single-mode radiation field with two-level atoms is described by a Hamiltoni- an trilinear in the boson operators.It is shown that the dynamics of the system can be determined near- ly exactly when mode 1 is strong。
