研究了二能级原子与单模经典电磁场的相互作用问题。研究发现，初始粒子数反转的模型表现出混沌行为，随着原子数密度的增加，混沌行为变得更强。通过傅里叶分析和最大李雅普诺夫指数对混沌进行了表征。然而，在行波近似中，没有混沌的预测。
The problem of a collection of two-level atoms interacting with a single-mode classical electromagnetic field is considered. It is found that the model with an initial population inversion exhibits chaotic behavior that becomes stronger for higher atomic number density. The chaos is characterized by Fourier analysis and the maximal Lyapunov exponent. In the rotating-wave approximation, however, there is no prediction of chaos.
