GRK 2079: Cold Controlled Ensembles in Physics and Chemistry
Final Report Abstract
The International Research Training Group (IRTG 2079) "Cold Controlled Ensembles in Physics and Chemistry" was both scientifically and in terms of doctoral training a great success, and has significantly enriched the activities within the contributing research groups at the University of Freiburg and at UBC in Vancouver. The key aspect of an improvement in the education and the graduation of doctoral researchers is clearly evidenced in the comparison of IRTG CoCo graduates with their fellow students locally in Freiburg, but outside the IRTG Coco, or even nationwide: the IRTG CoCo researchers graduated earlier and with better grades. Furthermore, we were able to bring an above-average portion of female researchers to graduation. On a qualitative level, the success of the IRTG CoCo is evidenced by the following features: (1) The underlying science: the established collaborations and the continuous scientific exchange and discussions included in the IRTG qualification program have, first and foremost, led to high-level und internationally recognized research projects which could only be established in the combination of the involved groups at UF and UBC. This is also shown by the output of publications and the large number of contributions to conferences and workshops. (2) The interdisciplinary mix of projects between physics and chemistry was just right for the doctoral researchers. We managed very successfully to invoke in each IRTG participant a feeling of passion and competence for their own project and interest in that of their peers. In this way, everyone was exposed to physics and chemistry beyond the own specific area of research. Moreover, the opportunities within the IRTG fertilizing ideas by bringing in many external guests as well as presenting work and discussing projects at conferences and workshops, provides precious added value to own research and qualification. (3) The international and intercultural spirit was deeply entrained into the doctoral work, not only directly during exchange visits, but also to a large extend during the continuous interactions and discussions as a result of IRTG events. Thus, numerous further projects and joint publications were established beyond the duration of the IRTG. (4) The IRTG formed a community of friends beyond national borders, which very much deepens the cultural exchange, but also allows participants to better calibrate their own achievements. In simpler words, the participants know and help each other. (5) The IRTGs in Freiburg and in particular the IRTG CoCo have influenced the graduation regulations of the Faculty of Mathematics and Physics of the University of Freiburg by their successful quality management structures. Co-supervision, supervision agreements etc. that are now part of the graduation regulations were to a large extend triggered and discussed with IRTG coordinators. It is important to stress that the IRTG doctoral researchers were very satisfied with the IRTG program and its opportunities, as demonstrated by the evaluation surveys. The networking possibilities as well as the qualification and study program were well accepted. Since 2016, the IRTG has developed numerous highly qualified scientists working on research projects at universities, in industry and at world-renowned research institutions. Unfortunately, the time of the extension period was dominated by the worldwide pandemic situation and has hampered travel and exchange activities with UBC in this final stage. However, in comparison with the great achievements of the whole program this is only a very minor downstroke.
