我们研究了三个远距离原子的贝尔非定域性动力学，其中两个原子被囚禁在一个单模腔中，第三个原子被囚禁在另一个远距离单模腔中。用Tavis Cummings和Jaynes Cummings模型研究了原子与腔模的相互作用。这里引入了两个单模腔来模拟三个原子的两个不同的环境。分别从Svetlichny和WWZB两个不同的角度研究了三方非局域关联。结果表明，在W态和GHZ态的初始条件下，将发生三方贝尔非定域猝死。详细的结果表明，当受到环境影响时，GHZ态的三体非定域性比W态的非定域性更强。
We study the Bell-nonlocality dynamics of three remote atoms, two of which are trapped in one single-mode cavity and the third atom is trapped in another remote single-mode cavity. The interactions between the atoms and the cavity modes are studied via Tavis Cummings and Jaynes Cummings models. Here, the two single-mode cavities are introduced to simulate two different enviroments of the three atoms. The tripartite nonlocal correlations are studied in terms of the Svetlichny inequality and the WWZB inequality, respectively. The results show that the tripartite Bell-nonlocality sudden death will occur for the W state and GHZ state initial conditions. The detailed results demonstrate that the tripartite nonlocality of GHZ state is more robust than that of W state when suffering from the effect of environments.
