摘要
本文研究了两个双能级原子与双模真空腔场具有不同耦合常数(g_1≠g_2)时的自发辐射线型.一般情况下,两原子系统的"双模真空场拉比劈裂"存在对称十峰结构;在 R=g_2/g_1从0.25增加到0.75的过程中,自发辐射线型交替出现对称八峰和十峰结构;双模真空场中单原子的对称双峰结构以及两等同原子的对称六峰结构可作为特例得出.另一方面,本文给出了上述谱特性的物理解释.
The spontaneous-emission line shape of two atoms interacting with two-mode vacuum cavity field with different coupling constants(g_1≠g_2)is studied.In general,the'two-mode vacuum-field Rabi splitting'of two-atom system consists of symmetric ten peaks;The spontaneous-emission line shape shows symmetric eight peaks and ten peaks alternately,with the increase of R=g_2/g_1 from 0.25 to 0.75;The symmetric two-peak structure for one atom and six-peak structure for two identical atoms in two-mode vacuum field may be obtained as two examples.On the other hand,the above properties of spectrum is physically explained.
