在Λ型三能级原子系统模型的基础上,采用半经典的密度矩阵方法分析了87Rb气体的相干布居囚禁现象。数值模拟结果显示,当两束相干激光频率差等于87Rb原子的两个基态超精细结构子能级频率差时,87Rb气体具有相干暗线和相干微波辐射的特性... 在Λ型三能级原子系统模型的基础上,采用半经典的密度矩阵方法分析了87Rb气体的相干布居囚禁现象。数值模拟结果显示,当两束相干激光频率差等于87Rb原子的两个基态超精细结构子能级频率差时,87Rb气体具有相干暗线和相干微波辐射的特性。它们可以作为相干布居囚禁原子频标的鉴频物理基础。最后简要分析了两种相干布居囚禁原子频标的各自特点和实验装置结构。 展开更多

Abstract The reduced dynamics of a V-type three-level atom in a structure reservoir is presented, which has the exact solution in certain special condition. The Markovian and non-Markovian master equations for this composite system are solved and compared with the exact solution. The solving approach can be directly generalized to the solution of a V-type multilevel system dynamics interacting with a reservoir. The results further testify that these two kinds of master equations are exploited in different coupling regime, providing guidance for further application of these variants master equations to solve multilevel system dynamics without the exact solution. 展开更多
