| 摘 要： | 利用全量子理论,研究了压缩真空场与V型三能级原子依赖强度耦合作用系统中原子的偶极压缩效应.采用数值计算的方法,讨论了初始场压缩因子r、光场与原子的耦合强度g对原子偶极压缩的影响.研究结果表明,随着r的增大,原子偶极压缩的次数逐渐减少,且随时间的演化逐渐消失,但最大压缩量无明显的变化;而g的增大使原子的偶极压缩效应的次数增多,而压缩持续时间减少.

| Abstract: | The time evolution of atomic dipole squeezing in the intensity-dependent coupling interaction between squeezing vacuum state and V-type three-level atom is studied using the quantum theory.The effects of the squeezing degree r of initial field and the coupling constant g are discussed by the method of the numerical calculations.The result shows that when r increases,the times of atomic dipole squeezing decrease gradually and vanish with the time evolution,but the maximum of degree has no evident change;the times of atomic dipole squeezing increase,while the duration is shortened with the increase of g. |
