In our group, we study the physics of ultra-cold atoms in the laboratory as well as in the microgravity environment of the drop tower Bremen. These free fall experiments provide a unique approach towards tests of gravity theory and quantum physics in a new parameter regime. We are also engaged in the development of new concepts and tools for space- and ground-based matter-wave interferometry, as well as tests of fundamental physics using these quantum sensors... Our research focusses on problems at the interface between Quantum Theory-the theory of matter-and General Relativity-the theory of gravity. These two theories form the main pillars of modern fundamental physics, tough they partially rest on mutually incompatible principles. We wish to gain a better understanding as to how these principles have to be modified in order to achieve unification by asking simple questions regarding experimentally accessible situations to which both theories apply. We are also interested in..
