论文摘要
在谐振Jaynes-cummings模型中存在原子场相关性和单模非古质的动力学，使用负面和纠缠潜力的一组初始状态研究。该研究揭示了该模型中存在的三种不同类型的非古老性之间的相互作用，并确定通过原子场相关性在田间和原子之间不断交换非古质性。此外，可以观察到，纠缠势并不能捕获所有单模非古老性，并且在梁分离器的输出处还存在一些残留的单模状态，而单模单模式状态并未由单模非classicality在Asboth的标准中进行定量映射。添加了额外的光束拆分器层以耗尽所有非经典性，并揭示几乎所有残留的非经典性都被三层梁拆分器捕获。此外，如果原子 - 场相关性最大，则原子和场的还原状态在FOCK基础上具有零（非零）量子相干性，如果磁场（或原子）最初具有零（非零）量子相干性。
Dynamics of atom-field correlations and single-mode nonclassicalities present in the resonant Jaynes-Cummings model are investigated using negativity and entanglement potential for a set of initial states. The study has revealed the interplay between three different types of nonclassicality present in the model and established that the nonclassicality is continuously exchanged between the field and atom through the atom-field correlations. Further, it is observed that the entanglement potential does not capture all the single-mode nonclassicality and there exists some residual nonclassicality in the reduced single-mode states at the output of the beam splitter which is not captured by the entanglement in which single-mode nonclassicality is quantitatively mapped in Asboth's criterion. Additional layers of beam splitters are added to deplete all the nonclassicality and to reveal that almost all the residual nonclassicality is captured with three layers of beam splitters. Further, the reduced states of the atom and field have zero (non-zero) quantum coherence in the Fock basis when the atom-field correlations are maximum if the field (or atom) has zero (non-zero) quantum coherence initially.
