Experimental Gravitation and Quantum Optics

The experimental gravitation and quantum optics group at ZARM focuses on drop tower experiments with ultra-cold atoms (QUANTUS, PRIMUS) where we study the physics of these quantum systems in extended free fall. These free fall experiments provide a promising approach towards tests of gravity theory and quantum physics in a new parameter regime. We are also engaged in the modeling of such quantum systems and future fundamental physics tests in a microgravity environment. As a spin-off to our experiments with cold atoms, we also investigate the application of metrology instruments such as optical cavities or a frequency comb, which we apply as highly stable frequency references.
