行波控制下囚禁离子的质心运动

研究了一个受大失谐外加行波场周期驱动的两离子系统，采用数值计算和计算机模拟的方法分析了初始条件、阱频强弱以及相互作用时间对质心运动的影响，作出了囚禁离子质心的相空间轨道图，从中发现外部参数和离子的初始条件是囚禁离子质心做规则运动以及混沌运动的外部影响因素.

Center of Mass Motion of Trapped Ions under Control of Traveling-Wave

A two-ion system is studied,in which the trapped ions couple to a traveling-wave laser field.The authors analyze the influence aroused by different initial conditions and the trap frequencies as well as interaction time by taking numerical calculation and computer simulation methods.Meanwhile,the authors plot the orbits on phase space,and propose that the external parameters and initial conditions of trapped ions are the external influential factors for regular and chaotic motion of the trapped ion.
