随着时间的演化，原子与光场组成体系的纠缠度呈现出周期性变化规律。 - We present a measure for generating entangled state of atom - cavity field , which is prepared based on the two - photon jaynes - cummings model of atom - cavity field interaction
摘要该文提出了在双光子j - c模型中利用二能级原子与单模场的相互作用，制备出原子与光场的纠缠态。 - We call the new quantum phenomenon that ca n ' t be explained by classical theory non - classical feature of cavity field . it has been proved by experiment , that quantum states of cavity field can exhibit three non - classical features , i . e . photon antibunching effect , sub - poissonian statistics distribution , and squeezed states
在光场与原子相互作用的过程中会出现某些不能为经典理论所解释的新的量子现象，人们统称这些现象为光场的非经典效应，目前实验上所观测到的非经典现象有光子的反聚束效应、亚泊松分布和光场的压缩效应。 - We clarified that if the three - level atom and the two - mode cavity field are all in the coherent superposition state , the different transition processes interfere each other , the emission spectrum exhibits phase sensitivity . second , the phase properties of the two - mode su ( 2 ) coherent field interacting with a - type three - level atom and the two - mode su ( 1 , 1 ) coherent field interacting with two atoms are investigated
我们考察了双模su ( 2 )相干场与型三能级原子相互作用系统以及双模su ( 1 ， 1 )相干场与双原子相互作用系统中双模光场的相位性质，证明了光场每个j迄凶博士学位论文docioraldisser ” i人lion - 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
