论文摘要
我们在准1D偶极bose气体和量子液滴中查看深色孤子。我们得出了一个类似于平均场效应的毛状孔状方程的分析词素解。结果表明，偶极相互作用有一定的临界值，而孤子孤子的宽度有所不同。此外，还有一个遥不可及的孤子的奇特解，其密度最小为非零密度。我们还显示了这些孤子的能量谱，并出现了其他激发子分支。最后，我们执行一系列数值实验，揭示了量子液滴内的深色孤子的共存。
We look into dark solitons in a quasi-1D dipolar Bose gas and in a quantum droplet. We derive the analytical solitonic solution of a Gross-Pitaevskii-like equation accounting for beyond mean-field effects. The results show there is a certain critical value of the dipolar interactions, for which the width of a motionless soliton diverges. Moreover, there is a peculiar solution of the motionless soliton with a non-zero density minimum. We also present the energy spectrum of these solitons with an additional excitation subbranch appearing. Finally, we perform a series of numerical experiments revealing the coexistence of a dark soliton inside a quantum droplet.
