effective hamiltonian meaning in English
有效哈密顿量
Examples
- 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
从多能级原子与多模光场的相互作用哈密顿量出发，导出了型三能级原子与双模光场的相互作用哈密顿量.在大失谐条件下将其化成等效的二能级形式双模喇曼耦合模型.提出了该模型的一个改进型等效哈密顿量.该哈密顿量由两部分构成：一部为通常所谓的等效哈密顿量，另一部分描述原子能级的动态斯塔克移动.研究表明，在双模喇曼耦合模型的研究中，只考虑前者是不够的，还必须考虑后者.最后，我们研究了该系统中原子的动力学行为，发现崩塌-复苏的数目、崩塌时间和复苏时间均呈现新的特性
