大失谐下纠缠原子与场作用过程中的光场特性

The property of the optical field interacting with entangled atoms

研究在大失谐条件下两全同二能级纠缠原子与相干态光场相互作用过程中系统的光场特性,采用时间演化算符和数值计算方法讨论了系统参数对系统光场特性的影响。研究表明:单模相干光场和两全同二能级纠缠原子在大失谐作用条件下,无论如何调整系统参数,都无法使光场压缩。

The property of the optical field interacting with two identical entangled atoms is investigated, where the interaction between atoms and cavity mode is a highly detuned one. The effect of the system parameters on the property of the optical field is discussed via time evolution operators and numerical calculation. The result shows that, in this highly detuned system, the optical field cannot manifest squeezing effect under any system parameter.
