中文摘要：
研究了三个二能级原子与共同热库发生相互作用的系统纠缠动力学演化．采用三体负本征值来描述系统间纠缠，通过数值计算分析了初始状态和原子间偶极．偶极相互作用对系统间纠缠演化的影响．结果表明，初始状态的原子相位可以控制量子干涉现象；长时间演化下原子的激发态布居出现俘获现象；通过调节偶极．偶极相互作用强度，可以提升三原子间纠缠．
英文摘要：
Entanglement dynamical evolution of three two-level atoms coupled to a common environment is mves~lgateo, vve utilize the tripartite negativity to quantify entanglement and analyze the effect of the initial state, pairwise dipole-dipole interactions on the entanglement dynamical properties of the system by means of numerical calculations. Results show that a novel quantum interference can be controlled by the relative phase of initially entangled states of the atoms. And the excited-state population can be trapped in the long time limit. Besides, the tripartite entanglement can be enhancedby choosing the appropriate conditions.
