Effectof the Nonlinear Coupling Intensity on Quantum Phase Properties of Light Field in the Generalized Jayne-Cummings Model with a Kerr Medium
【摘要】 研究了由于 Jaynes- Cum ming模型和非谐振子模型构成的组合模型中光场的量子相位特性 ,计算了光场 - Kerr介质非线性耦合常数与光场 -原子耦合常数的比值在弱 ( ng- 2 >>n2 x2 )。中性 ( ng- 2～ n2χ2 )和强( ng2 <<n2χ2 )非线性耦合情形对光场相位分布、相位平均值和相位涨落的影响 ,并将结果与 Jaynes-Cum mings模型和非谐振子模型的结果进行了比较
【Abstract】 The quantum phaseproperties of lightfield in the combined model joining the Jaynes- Cummings and the anharmonic osocillator modelsare studied.The effectof theproportionality value of the field- Kerrmedium coupling constant to the field- atom coupling constant.in weak (ng2 >>n2 g2 ) ,neutral (n2 g2 ～ n2 g2 ) and strong(ng2 <<n2χ2 ) nonlinearcoupling cases.On the phase distributionsand themean valueand thevariance of phase of the light field are computed numerically.The results are compared to earlier results both in the Jaynes- Cummingsmodel and the anharmonic oscillator model.
【Key words】 generalized Jaynes- Cummings model； phase distribution； mean value of the phase； variance of the phase； weak,neutral and strong nonlinearcoupling；
