The aim of QUDIPMOL is the creation, understanding and control of a dipolar quantum gas formed by heteronuclear bialkali molecules. Ideally, all molecules in the gas are characterized by a single, identical rotational, vibrational and translational quantum state, which is achieved by synthesizing the molecules from atomic quantum gases using light fields (photoassociation) and magnetic fields (Feshbach linking). Atom-dimer and dimer-dimer scattering will be investigated in great detail in order to identify routes towards control of molecular collisions in a many-body system (ultracold chemistry), and effects of the interactions on the dynamics of the polar quantum gas will be explored. The complexity of the experimental and theoretical challenges, which are central to the key issues of EuroQUAM, requires combined approaches ranging from Atomic, Molecular, Optical Physics over Condensed Matter Physics to Quantum Chemistry. Therefore, QUDIPMOL joins five experimental and four theoretical groups representing unique and complementary expertise in these areas of research in a well balanced mixture of senior and young researchers as Principal Investigators. Key experimental approaches towards molecular quantum gases include studies of ultracold collisions, photoassociation, Feshbach formation, high-resolution molecular spectroscopy, sensitive molecular diagnostics, and the fine arts of creating and handling quantum degenerate gases. The theoretical groups share their knowledge on advanced molecular structure calculations, dynamics of reactive scattering and many-body quantum physics of highly correlated systems. Intense exchange among and between experimental and theoretical groups builds upon well-established collaborations between the partners. Results of the research in QUDIPMOL will have important impact on other EuroQUAM projects and will further strengthen Europe's competitive, internationally well-established position in the field of ultracold molecular quantum gases.

QUDIPMOL的目标是创造，理解和控制由异质双碱分子形成的偶极量子气体。理想情况下，气体中的所有分子都具有单一的相同的旋转，振动和平移量子态，这是通过使用光场（光缔合）和磁场（Feshbach链接）从原子量子气体合成分子来实现的。原子-二聚体和二聚体-二聚体散射将被详细研究，以确定在多体系统（超冷化学）中控制分子碰撞的路线，并将探索极性量子气体动力学上的相互作用的影响。实验和理论挑战的复杂性是EuroQUAM关键问题的核心，需要从原子，分子，光学物理到凝聚态物理到量子化学的综合方法。因此，QUDIPMOL加入了五个实验组和四个理论组，代表了这些研究领域的独特和互补的专业知识，高级和年轻研究人员作为主要研究人员的平衡混合。对分子量子气体的关键实验方法包括超冷碰撞，光缔合，Feshbach形成，高分辨率分子光谱学，灵敏的分子诊断学，以及创造和处理量子简并气体的艺术研究。理论小组分享他们在高级分子结构计算，反应散射动力学和高度相关系统的多体量子物理学方面的知识。实验组和理论组之间的激烈交流建立在合作伙伴之间良好的合作基础上。QUDIPMOL的研究成果将对其他EuroQUAM项目产生重要影响，并将进一步加强欧洲在超冷分子量子气体领域的竞争力和国际地位。
