Cavity-Induced Self-Trapping of a Bose Josephson Junction

我们调查一个 Bose Josephson 连接自我套住，它散地被联合到一个驾驶的光洞。导致洞的非线性是介绍经分解，并且它的效果导致外观为在 Josephson 摆动政体的 Bose 爱因斯坦冷凝物自我套住。另外，在那里存在在非线性之间的竞争为出现由 interatomic 相互作用并且由驾驶的洞导致了自我套住。我们的结果证明驾驶的洞能作为一个可能的工具被利用生产为有弱 interatomic 的冷凝物自我套住相互作用。

We investigate the self-trapping of a Bose Josephson junction, which is dispersively coupled to a driven optical cavity. The cavity-induced nonlinearity is presented analytically, and its effect results in the appearance of the self-trapping for the Bose-Einstein condensates in the Josephson oscillation regime. In addition, there exists competition between the nonlinearities induced by the interatomic interaction and by the driven cavity for the emergences of self-trapping. Our results show that the driven cavity can be utilized as a possible tool to produce the self-trapping for the condensates with weak interatomic interaction.
