Controllable Superfluid Properties of Dipolar Matter-Wave Bright Solitons

由于孤子如此不分散，它们是令人感兴趣的系统，被认为是杂质的物质波陷阱。在这种情况下，吸引人的人场势提供了一种限制结构，如果使用解序列解将其中的几个结合在一起，就可以研究这种系统中的相干杂质动力学。在这项工作中，我们证明了这个问题的解是稳定的，并且表现出有趣的隧道动力学。虽然最初的描述是关于耦合的Gross-Pitaevskii方程，但我们也发展了一个有效的类Rabi模型来解释种群动力学。

As solitons so not disperse, they are intriguing systems to consider as matter-wave traps for impurities. In this case an attractive man-field potential provides a confining structure and if one combines several of them by using solution-train solutions, one can study coherent impurity dynamics in such systems. In this work we showed that solutions for this exist that are stable and display interesting tunneling dynamics. While the initial description is in terms of coupled Gross-Pitaevskii equations, we also develop an effective Rabi-like model that explains the population dynamics.
