原子运动对双光子JC模型能级分裂的影响(英文)

研究了双光子ＪＣ模型中原子运动对能级分裂的影响及其在原子辐射谱中的反映．结果发现，当原子具有确定的动量和光场处于Ｆｏｃｋ态时，每个原子能级具有两个值，原子辐射谱的谱线相应地分裂为两条．原子分裂能级的间隔主要依赖于原子和光子的动量的差值．

Resonance Fluorescence in Two—Photon JC Models Analyzed by Supersymmetric Transformation

Resonance fluorescences of two-photon two-level and two-photon three-level atoms driven by laser are investigated with supersymmetric transformation.It is shown that the spectrum of fluorescent light obtained from the supersymmetric transformation is more accurate and the physical process shown by this method is clearer than that from dress transformation.
