Abstract
We variationally determine the dynamics of bright soliton trains composed of harmonically trapped Bose-Einstein condensates with attractive interatomic interactions. In particular, we obtain the interaction potential between two solitons. We also discuss the formation of soliton trains due to the quantum mechanical phase fluctuations of a one-dimensional condensate.
摘要
我们通过变分法确定了由具有吸引性原子间相互作用的简谐捕获玻色-爱因斯坦凝聚体组成的亮孤子列的动力学。特别地，我们得到了两个孤子之间的相互作用势。我们还讨论了由于一维凝聚体的量子力学相位涨落导致的孤子列的形成。
