压缩真空场与原子非线性作用系统中原子的量子特性

The quantum properties of the atom in the nonlinear interaction between squeezing vacuum state field and atom

研究了附加克尔介质的压缩真空场与二能级原子依赖强度耦合相互作用系统中原子的反转特性 ,并采用密度算符间的距离研究了该模型中原子量子态的演化规律。详细地讨论了克尔非线性作用的强度以及初始压缩真空场的压缩度对原子反转和原子量子态演化的影响。

The properties of the atomic inversion and the atomic state evolution in the intensity-dependent coupling interaction between squeezing vacuum state field and atom with an additional kerr medium are investigated by using the distance between density operators. The influences of nonlinear interaction intensity of kerr medium and the squeezing degree of initial squeezing vacuum state field on the quantum properties of the atom are discussed.
