| 摘 要： | 利用concurrence的纠缠度量方法,研究了两个全同的二能级原子与双模腔场共振相互作用时原子与原子纠缠演化.研究结果表明两原子的纠缠演化受到原于初态类型、光子数的影响,进一步分析了原子间的纠缠猝死现象与原于—腔场的纠缠转移关系.

| Abstract: | By using the concurrence method,the entanglement evolution of two entangled atoms which are in two levels is studied,that interact with two-mode cavity field.The results show that the entanglement evolution of two atoms is influenced by the initial state of the two-atom and the two-mode cavity field.Furthermore,the relations of entanglement sudden death and the entanglement transfer problem are analyzed. |
