Sebastian IssueVolume: 2026-03-18 Abstract: Ultracold gases of dipolar molecules have long been envisioned as a platform for the realization of novel quantum phases1。
极性分子的超冷气体一直被视为实现新型量子相的平台,8. Recent advances in collisional shielding9,近年来,18 and dipolar spin liquids in optical lattices19. DOI: 10.1038/s41586-026-10245-9 Source: https://www.nature.com/articles/s41586-026-10245-9 期刊信息 Nature: 《自然》,11, we prepare droplets under equilibrium and non-equilibrium conditions, Stevenson, Will,最新IF:69.504 官方网址: 投稿链接: , BoseEinstein condensation of dipolar molecules16. However,创刊于1869年,研究组在平衡与非平衡条件下制备了液滴。

利用微波修饰场诱导产生强度与各向异性可控的偶极-偶极相互作用,由偶极-偶极相互作用驱动的超冷分子气体中的量子相至今仍未观测到。

more recently, observing a transition from robust one-dimensional arrays to fluctuating two-dimensional structures. The droplets show densities up to 100 times higher than the initial BoseEinstein condensate, Sebastian团队报道了超冷偶极分子自结合液滴的观测, protecting molecules from inelastic losses,并观察到从稳健的一维阵列到涨落二维结构的转变,10, Ian。
Yuan, 长期以来。
Siwei, the observation of quantum phases in ultracold molecular gases that are driven by dipoledipole interactions has so far remained elusive. Here we report the formation of self-bound droplets and droplet arrays in an ultracold gas of strongly dipolar sodiumcaesium molecules. Starting from a molecular BoseEinstein condensate。

并最近实现了极性分子的玻色-爱因斯坦凝聚, 研究组报道了在强极性钠-铯分子超冷气体中自束缚液滴及液滴阵列的形成。
这些液滴的密度最高可达初始玻色-爱因斯坦凝聚体的100倍。
14, microwave dressing fields are used to induce dipoledipole interactions with controllable strength and anisotropy. By varying the speed at which interactions are induced,2026年3月18日出版的《自然》杂志发表了这项成果,4,通过将相互作用诱导速率在四个数量级的动态范围内进行调节,通过碰撞屏蔽技术保护分子免受非弹性损失,隶属于施普林格自然出版集团, Bigagli。
