论文摘要
量子状物质状态已在一系列具有超速玻色气体的实验中实现。使用分析和数值方法的结合，我们确定了超出均值场二进制冷凝物中暗孤子存在的特定标准，揭示了如何在排斥和有吸引力的相互作用中存在这些激发，后者导致了深色量子液滴与深色溶剂和量子液滴之间的属性中间的深度量子液滴。这些激发的现象学在模型的完整参数空间中进行了探索，揭示了激发的新空间曲线，该兴奋与Zakharov-Shabat（ZS）Soliton显着不同。导致负有效质量在量子波动的存在下得到增强。最后，探索了激发对的动力学，在有吸引力的制度中显示了不可积分的动力学和深色孤子界。
Quantum liquid-like states of matter have been realized in an ongoing series of experiments with ultracold Bose gases. Using a combination of analytical and numerical methods we identify the specific criteria for the existence of dark solitons in beyond-mean-field binary 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 phenomenology of the these excitations are explored within the full parameter space of the model, revealing the novel spatial profile of the excitation that differs significantly from the Zakharov-Shabat (ZS) soliton; leading to a negative effective mass that is enhanced in the presence of the quantum fluctuations. Finally the dynamics of pairs of the excitations are explored, showing non-integrable dynamics and dark soliton bound-states in the attractive regime.
