摘要
文章研究了驱动三阱系统中双原子的隧穿动力学。在高频近似下基于Floquet理论我们解析得到了共振情况下系统的准能量及Floquet态,并分析了Floquet态描述下原子处于各Fock的几率与外场驱动参数的关系,发现零准能量对应的Floquet态在一定的驱动参数下完全局域于单个Fock态,其相应参数下系统的时间演化展示了原子隧穿的相干破坏效应。
We investigate tunneling dynamics of two atoms in a driven triple- well system in this paper. In high- frequency approximation,we obtain the quasi- energy and Floquet state and the relationship between probabilities of Fock state and driving parameters is shown under resonance case,in which the Floquet state can be located in single Fock state for some driving parameters and the corresponding time- evolution of Fock state exhibits effect of coherent destruction of tunneling.
