In the last years, dipolar gases have developed to one of the most active and promising research topics in the very competitive field of ultracold gases. Bose-Einstein condensates and degenerate Fermi gases of highly magnetic atoms are nowadays routinely prepared in the laboratory. Great progress has been achieved as well in the preparation of dipolar gases made of ultracold polar molecules. Dipole-dipole interactions lead to exciting novel physics both at the few- and many-body level that recent experiments are just starting to unveil. The joint Research Unit FOR 2247 of DFG and FWF, combining the expertise of leading research groups working on dipolar gases, has decisively contributed to recent progress, fostering the competitiveness of Germany and Austria in the challenging field of dipolar quantum gas physics. Within the upcoming funding period, we plan to deepen even further our synergies and collaborations and to build on our established common platform to address novel intriguing questions at the forefront of modern quantum physics. In particular, we plan to combine and coordinate our research activities on dipolar gases along our two main scientific objectives: * We will deepen our understanding of two- and few-body collisional processes in dipolar gases, including collisional processes between ground state molecules and in spin mixtures of highly magnetic atoms. This will allow us to engineer two- and few-body collisional processes preparing the ground for the observation of a wealth of novel manybody scenarios. * We will investigate theoretically and experimentally novel many-body phenomena in dipolar gases. We will put particular emphasis to particularly intriguing topics, including dipolar rotons, quantum droplets, supersolids, dipolar lattice gases, and superfluidity in dipolar fermions. We will maintain and further improve our established collaborative frame, encouraging lively discussions, the interchange of know-how, the development of novel ideas and tools among our groups, and the creation of new links and cooperations within our Unit. We will structure these networking activities by means of our established Joint Virtual Institute, which organizes several initiatives, including a common IT infrastructure, a visitors program, yearly workshops, student visits, and coordinated task forces.
