论文摘要
横向泵送的玻色网凝结物（BEC）的系统耦合到有损耗的环腔可以有利于超固体稳态。在这里，我们发现在这种驱动的系统中，Supersolid Gap Soliton的存在。通过数字求解平均场原子 - 腔场耦合方程，已经确定了一些不同家族的缝隙孤子。还研究了它们的动力学特性，包括稳定性，繁殖和孤子碰撞。由于反馈原子 - 引导场相互作用，与静态光学晶格中通常的BEC隔离单子相比，这些超固体间隙孤子显示出许多新功能。
The system of a transversely pumped Bose-Einstein condensate (BEC) coupled to a lossy ring cavity can favor a supersolid steady state. Here we find the existence of supersolid gap soliton in such a driven-dissipative system. By numerically solving the mean-field atom-cavity field coupling equations, gap solitons of a few different families have been identified. Their dynamical properties, including stability, propagation and soliton collision, are also studied. Due to the feedback atom-intracavity field interaction, these supersolid gap solitons show numerous new features compared with the usual BEC gap solitons in static optical lattices.
