无旋转波近似下单个超冷离子与一束驻波型激光相互作用的动力学

Dynamics of the interaction between a trapped ultracold ion and a standing wave laser without rotating wave approximation

在相互作用表象中 ,研究了Lamb Dicke区内单个超冷囚禁离子与一束驻波型激光相互作用的动力学行为。由于没有引入旋转波近似 ,离子的运动随着Lamb Dicke参数 η和Rabi频率Ω的增大趋向于混沌。所得结果与旋转波近似下的结果作了比较。

In an interaction representation, we study the dynamics of the interaction between a trapped ultracold ion and a standing wave laser within the Lanb Dicke limit. As the rotating wave approximation is not introduced the ions motion becomes more and more chaotic with the increase of the Lamb Dicke parameter and Rabi frequency. Finally, we make a comparison of our results with those under the rotating wave approximation.
