| 摘 要： | 在初态为Bell态的两个二能级原子与双模腔场的耦合系统中，我们研究了其子系统纠缠转移时两原子的能量与其纠缠演化之间的关系。结果表明：两者的关系是密不可分的。而且，我们还讨论了原子间的偶极-偶极相互作用和腔场中的光子数对这种关系的影响。

| Abstract: | We study the relation between energy and entanglement in an entanglement transfer problem in the two-mode cavity QED. The model consists of two two-level atoms which are initially prepared in a Bell-like state and locally coupled with the two-mode cavity. We show that the atomic entanglement dynamics is closely related to that of their energy. Moreover, we also discuss the influence on the relation by means of considering the dipole-dipole interaction between atoms and the photon numbers in the two-mode cavity field. |
