原子运动对双光子JC模型能级分裂的影响(英文)

ENERGY SPLIT OF TWO-PHOTON JAYNES-CUMMINGS MODEL WITH ATOMIC MOTION

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．

The energy split and the emission spectra of two-photon Jaynes-Cummings model with the atomic motion are studied. It is found that the energy of each atomic state has two possible values with same differences when the field is in a Fock state and the atom has a definite momentum initially;the emission spectra exhibit the peak split structures, reflecting the energy split induced by the atomic motion. The energy split depends mainly on the momental difference between the atom and the photon.
