In this paper, the quantum properties of a two-level atom interaction with squeezed vacuum reservoir is throughly analyzed. With the aid of the interaction Hamiltonian and the master equation, we obtain the time evolution of the expectation values of the atomic operators. Employing the steady-state solution of these equations, we calculate the power spectrum and the second-order correlation function for the interaction of two-level atom with squeezed vacuum reservoir. It is found that the half width of the power spectrum of the light increases with the squeeze parameter, . Furthermore, in the absence of decay constant and interaction time, it enhances the probability for the atom to be in the upper level.

两能级原子与压缩真空容器的相互作用

本文通过对压缩真空容器中两能级原子相互作用的量子特性进行了分析。借助相互作用的哈密顿量和主方程，我们获得了原子算子期望值的时间演化。利用这些方程的稳态解，我们计算出了两能级原子与压缩真空容器相互作用的功率谱和二阶相关函数。可以发现，光的功率谱的半峰宽度随挤压参数增大。此外，在没有衰减常数和相互作用时间的情况下，它增加了原子处于较高能级的可能性。
