论文摘要
我们研究了在Kerr样培养基存在下移动的三级Lambda Rubidium Atom与单个模式腔场之间的相互作用。我们得出原子系统运动的基本方程式，并表明它在旋转波近似（RWA）中是可以解决的。研究了该系统的动量增量，动量扩散和Mandel Q参数。我们从数值上研究了Kerr样培养基对先前统计特性的演化的影响，在确切的谐振和非共鸣的情况下，原子最初是在动量特征态和挤压状态下的场上制备的。发现Kerr培养基对其进化有重要影响。最后，得出结论和讨论。
We study the interaction between a moving three-level lambda rubidium atom and a single mode cavity field in the presence of Kerr-like medium. We derive the basic equations of motion for atomic system and show that it is exactly solvable in the rotating wave approximation (RWA). The momentum increment, the momentum diffusion and the Mandel Q parameter of this system are studied. We investigate numerically the influence of Kerr-Like medium on the evolution of the previous statistical properties in the exact resonate and nonresonate case where the atom is initially prepared in a momentum eigenstate and the field in the squeezed state. It is found that the Kerr medium has an important effect on their evolution. Finally, conclusion and discussion are given.
