摘　　要：研究双lambda型结构原子与四个光场相互作用的量子系统,探讨双驱动场下,系统量子效应如何通过双驱动场的配合来实现调控;运用数值模拟的方法求解该系统密度算符的偏微分方程组,分析解稳态解发现与系统相关物理量与每个驱动场并不是独立关联的,而是两驱动场相互配合调控;发现利用两个驱动场能有效地协调控制该系统相应的物理效应。The quantum mechanics system of interacting between double lambda type four-lever atoms and four light fields is studied. How to realize quantum effect manipulation is investigated under double drive light fields. The partial differential equations are solved by using numerical simulation. The steady-state solution is analyzed. That physical quantity related to the system is not autocephaly correlated to the only one drive field is found and is controlled by the two drive field together. Physical effect can effectively is controlled by two cooperant fields.
