Quantum liquid-like states of matter have been realized in an ongoing series of experiments with ultracold Bose gases. By means of analytical and theoretical methods we identify the specific criteria for the existence of dark solitons in beyond-mean-field condensates, revealing how these excitations exist for both repulsive and attractive interactions, the latter leading to dark quantum droplets with properties intermediate between a dark soliton and a quantum droplet. The dark quantum droplet's physical characteristics are investigated, including calculation of the integrals of motion, revealing their sensitive dependence on physical parameters relevant to the current generation of experiments with quantum gases in the beyond-mean-field limit.

在一系列正在进行的超冷玻色气体实验中，已经实现了类量子液体态。通过分析和理论方法，我们确定了超平均场凝聚态中暗孤子存在的具体标准，揭示了这些激发如何存在于排斥和吸引相互作用中，后者导致暗量子液滴具有介于暗孤子和量子液滴。研究了暗量子液滴的物理特性，包括运动积分的计算，揭示了它们对与当前一代超平均场极限量子气体实验相关的物理参数的敏感依赖性。
