N个原子系统中的自发发射

SPONTANEOUS EMISSION IN THE N ATOMS SYSTEM

本文研究多模辐射场与N个两能级原子的相互作用。当初始状态为一个原子处于激发态其余原子都处于基态时，得到了自发发射过程中系统的动力学规律。并将计算结果与其他一些已知的理论结果进行比较。

N two-level atoms are considered in interaction with multi -mode radiation field. The dy namics of the system can be determined exactly for the case of spontaneous emission,when only one atom is initially excited. We compare the results with the known numerical and analytical re sults.
