Since the first Bose-Einstein condensate of ultracold atomic gases was realized experimentally in 1995, the research field of ultracold quantum gases has been extremely active and has expanded in many different directions. New areas of research are emerging at the borderlines of atomic and molecular physics, quantum optics, and condensed matter physics. However, this rapid evolution in the field of ultracold quantum gases is not adequately reflected in standard curricula. The daily work of a PhD student in both theory and experiment is now so specialized that a broad knowledge about the research field is lacking. To provide a common platform of understanding both theory and experiment in the field of ultracold quantum gases, we organize an international school for physics students. The main goal of the school is to provide a solid introduction to the field of ultracold quantum gases, which will be delivered by internationally recognized experts of the field. Depending on the Covid-19 pandemic the school will take place either fully online or in hybrid mode.
