研究了存在偶偶相互作用的两个二能级原子与共同单洛伦兹热库相互作用模型下的两体间的纠缠动力学行为。主要考虑了原子系统与环境存在初始关联时,两原子间的偶偶相互作用对纠缠动力学的影响,可以发现:偶偶相互作用一定时,马尔科夫环境下初始关联使原子与热库间的纠缠比原子间的纠缠衰减得慢,非马尔科夫环境下初始关联使原子间的振荡减弱;另外在马尔科夫热库中,随着偶偶相互作用的增强,两原子纠缠可以得到提升,而在非马尔科夫热库中,随着偶偶相互作用的增强,原子间及原子与热库间最终保持较大纠缠值。
The entanglement dynamical behaviors between two bodies were investigated in the model of two two-level atoms interacting with a common single Lorentz reservoir ,with the existence of dipole-dipole interaction .When atom system and environment existed initial correlation ,the effect of the dipole-dipole interaction of two atoms on the entanglement dynamics were considered .It was shown that ,when the dipole-dipole interaction was certain ,the initial correlation made the entanglement of atom-reservoir decay more slowly than that of atoms in Markovian environment .But in Non-Markovian environment the initial correlation decreased the oscillation of atoms .Furthermore ,in Markovian reservoir ,the entanglement between atoms increased with the strength of dipole-dipole interaction increasing ,but in non-Markovian environment ,the Entanglement of atoms and atom-reservoir remained larger with the strength of dipole-dipole interaction increasing .
