论文摘要
突破性实验已新探索了偶极量子液滴和超莫丁的引人入胜的物理。偶极混合物的最新实现为进一步的可能性开辟了可能性。我们表明，在相当普遍的条件下，第二个成分的存在催化了液滴成核和在原本未调制的冷凝物中的超压性。混杂混合物中的液滴催化，即使是出奇的小杂质掺杂，也可能发生，这是由局部旋转不稳定性引起的，这是由于掺杂依赖性偶极强度的掺杂依赖性修饰而触发的。催化机制可能会触发两流体超酚的形成，其特征在于每个成分的通常不同的超流体分数，这为偶性超酚类旋转物理学的未来研究开辟了有趣的可能性。
Breakthrough experiments have newly explored the fascinating physics of dipolar quantum droplets and supersolids. The recent realization of dipolar mixtures opens further intriguing possibilities. We show that under rather general conditions, the presence of a second component catalyzes droplet nucleation and supersolidity in an otherwise unmodulated condensate. Droplet catalyzation in miscible mixtures, which may occur even for a surprisingly small impurity doping, results from a local roton instability triggered by the doping-dependent modification of the effective dipolar strength. The catalyzation mechanism may trigger the formation of a two-fluid supersolid, characterized by a generally different superfluid fraction of each component, which opens intriguing possibilities for the future study of spin physics in dipolar supersolids.
