单原子微波激射器中的压缩

Squeezing in an one-atom maser

利用Jaynes-Cummings模型研究单原子微波激射器中光场的量子起伏,得到了场正交分量的方差的一般表达式。并讨论了一种常见初态的最佳压缩及其时间演化。作为例子,详细研究了初始为热平衡分布的裸原子系统的压缩行为。

The quantum fluctuation of light fiold induced by an one-atom maser is investigated by means of Jaynes-Cummings mode, and the general expressions for the variances of the quadrature components of the field are obtained. Optimum squeezing in a class basic states and the corresponding time evolution are demonstrated. As an example, squeezing in initial state with bare atomic system in the thermal equilibrium distribution is studied in detail.
