Significant progress has been made by Dalibard,Dupont-Roc and Cohen-Tannoudji in 1982,who argued that there exists a symmetric operator ordering between the operators of atom and field that renders the distinct contributions of vacuum fluctuations and radiation reaction to the atom\'s spontaneous emission and energy shift separately Hermitian.

这种不确定性的根源来自于相互作用哈密顿量中原子和场算符的排序问题。1982年，法国物理学家Dalibard，Dupont-Roc和Cohen-Tannoudji提出原子和场算符对称排序的方法，从而消除了这种不确定性，使得真空涨落和辐射反作用对原子自发辐射和能级移动的贡献都是厄米的。

It follows that the natural frequences of complete system not only reflect the natural frequences of elastic beam tail ro...
