我们回顾了最近的软核玻色系统的理论结果,并描述了低温超固体“液滴晶体”相,预测了广泛的软核相互作用。我们确定了粒子间相互作用的条件,使这种有趣的阶段可能,并概述其观察的建议。我们认为这是超固体的原型,至少在超冷原子组装的背景下。
We review recent theoretical results for soft-core Bose systems, and describe the low-temperature supersolid "droplet crystal" phase, predicted for a broad class of soft-core interactions. We identify the conditions on the inter-particle interaction that render such intriguing phase possible, and outline proposals for its observation. We argue this to be the prototypical supersolid, at least in the context of assemblies of ultracold atoms.
