【摘要】 研究了Kerr介质中双模SU(1,1)相干态场与A型三能级原子非共振相互作用系统中场模失谐量、克尔介质以及原子初态对原子布居概率和场的Cauchy-Schwartz不等式的影响。结果表明:失谐量将延长原子Rabi振荡崩塌与复苏的周期,并使两模关联趋于恒定的非经典相关;Kerr效应将增强光场的非经典相关的稳定性,缩短原子Rabi振荡崩塌与复苏的周期;原子初始状态明显影响两模间的非经典相关程度,而对原子布居概率的影响不明显。更多还原

【Abstract】 The influences of detuning, Kerr medium and initial atomic coherence on the atomic population and Cauchy-Schwartz inequality in the system of SU(1,1) coherent states interacting non-resonantly with a A-type three-level atom with Kerr medium are investigated. The results show that the detuning lengthens the cycle of collapse-and-reclairn of the atomic Rabi oscillation and induces steady nonclassical correlation. Kerr effects make the nonclassical correlation properties steady and shorten the cycle of collapse-and-revival of the atomic Rabi oscillation. The initial atomic coherence affects obviously on the nonclassical coherence degree between the two mode cavities, while the influence on the atomic population is not evident.更多还原
