非马尔可夫环境中不同耦合的双原子偶极-偶极相互作用效应

The effect of dipole-dipole interaction for two atoms with different couplings in non-Markovian environment

Yang Li, Jiang Zhou, Hong Guo

摘要:

利用非微扰方法,研究了两个二能级偶极-偶极相互作用原子与一个非马尔可夫库耦合时不同耦合强度的纠缠动力学.除了分析定态存在的条件外,我们还发现偶极-偶极相互作用虽然会破坏定态纠缠,但较强的偶极-偶极相互作用确实会抑制初始阶段的退纠缠。这些结果对今后纠缠的工程应用具有一定的指导意义。

英文摘要:

Using the nonperturbative method, we study the exact entanglement dynamics of two two-level dipole-dipole interacting atoms coupled to a common non-Markovian reservoir with different coupling strengths. Besides analyzing the conditions for the existence of steady state, we find, though the dipole-dipole interaction could destroy the stationary entanglement, that relatively strong dipole-dipole interaction does suppress the disentanglement in the initial period of time. These results are helpful for the practical engineering of the entanglement in the future.
