1. It is derived the hamiltonian for the interaction of a - type three - level atom with a two - mode quantum cavity field from the general interaction hamiltonian between a multi - level atom and a multi - mode radiation field , and reduce it into an effective two - mode raman - coupled mode under large detuning condition . it is proposed a modified effective hamiltonian for the two - mode raman - coupled model . it is found the time - dependent state vectors and present validity conditions for the involved interaction hamiltonians . it is shown that in the study of the two - mode raman - coupled model it is not enough to retain only the usually used effective hamiltonian , one must also take into account the ac stark shift of the atomic levels ( at least one of the levels ) . finally , it is studied the atomic dynamics in the interaction of a - type three - level atom with a two - mode quantum cavity field and in the two - mode raman - coupled model . it is found that the number of collapse - revivals , the collapse time and the revival time show new characteristics
   從多能級原子與多模光場的相互作用哈密頓量出發(fā)，導(dǎo)出了型三能級原子與雙模光場的相互作用哈密頓量.在大失諧條件下將其化成等效的二能級形式雙模喇曼耦合模型.提出了該模型的一個改進(jìn)型等效哈密頓量.該哈密頓量由兩部分構(gòu)成：一部為通常所謂的等效哈密頓量，另一部分描述原子能級的動態(tài)斯塔克移動.研究表明，在雙模喇曼耦合模型的研究中，只考慮前者是不夠的，還必須考慮后者.最后，我們研究了該系統(tǒng)中原子的動力學(xué)行為，發(fā)現(xiàn)崩塌-復(fù)蘇的數(shù)目、崩塌時間和復(fù)蘇時間均呈現(xiàn)新的特性
2. It's difficult to find effective hamiltonian in a sentence. 用effective hamiltonian造句挺難的
