FOR 2247: From few to many-body physics with dipolar quantum gases

在竞争激烈的超冷气体领域中，偶极气体是最活跃和最有前途的研究课题之一。偶极-偶极相互作用的长程和各向异性特性有望在近年来刚刚开始揭示的少体和多体水平上为偶极气体提供令人兴奋的新物理学。因此，对偶极气体的研究涵盖了一个非常广泛的领域，包含了许多方面，这是一个小组很难单独解决的。因此，拟议的研究单位的主要目标是通过结合两国从事偶极气体研究的主要研究小组的专业知识，促进德国和奥地利在具有挑战性的偶极量子气体物理领域的竞争力。该研究单位将创造新的协同效应和合作，并建立一个共同平台，以解决现代量子物理学前沿的新问题。我们计划结合和协调我们的研究活动，围绕三个主要的科学目标：-开发新的实验工具，用于创建和操纵高磁性原子和极性分子的简并气体。-二体和少体碰撞过程（如反应性和非反应性碰撞）的研究和建立一个通用工具箱，用于工程原子和分子的偶极气体的二体和少体性质。-多体偶极物理的理论和实验研究，特别强调新的现象，如质子激发，层间复合材料和超固体。我们坚定地致力于建立一个协作框架，在我们的团队之间建立新的联系和坚实的合作，鼓励活跃的讨论，知识的交流，以及在我们的团队之间开发新颖的想法和工具。我们将通过一个联合虚拟学院来组织这些网络活动，该学院将组织若干举措，包括共同的IT基础设施、访客计划、年度研讨会、学生访问和协调工作组。

Dipolar gases constitute one of the most active and promising research topics in the very competitive field of ultracold gases. The long-range and anisotropic character of the dipole-dipole interaction is expected to result in an exciting novel physics for dipolar gases both at the few- and many-body level, which is just starting to be unveiled in recent years. Hence, research on dipolar gases covers a very broad area, containing many aspects that a single group will hardly be able to address alone. The main objective of the proposed Research Unit is thus to foster the competitiveness of Germany and Austria in the challenging field of dipolar quantum gas physics by combining the expertise of leading research groups working on dipolar gases in our two countries. The Research Unit will allow to create new synergies and collaborations, and to build a common platform to address novel questions at the forefront of modern quantum physics. We plan to combine and coordinate our research activities along three main scientific objectives:- The development of novel experimental tools for the creation and manipulation of degenerate gases of highly magnetic atoms and polar molecules.- The investigation of two- and few-body collisional processes (such as reactive and non-reactive collisions) and the establishment of a common toolbox for engineering two and few-body properties of dipolar gases of atoms and molecules.- The theoretical and experimental investigation of many-body dipolar physics with particular emphasis on novel phenomena such as roton excitations, inter-layer composites, and supersolids.We are strongly committed to establish a collaborative frame that will create new links and solid cooperation between our teams, encouraging lively discussions, the interchange of know-how, and development of novel ideas and tools among our groups. We will structure these networking activities by means of a Joint Virtual Institute, which will organize several initiatives, including a common IT infrastructure, a visitors program, yearly workshops, student visits, and coordinated task forces.
