Quantum bubbles are systems in which atoms are confined to a two-dimensional closed surface. They enable the study of phenomena like vortices, collective modes, and self-interference during expansion. These bubbles are typically created using radiofrequency (RF) dressed potentials and form more naturally in microgravity. However, inhomogeneities in static and RF magnetic fields can alter this advantage.
The Quantumania project adapts the MAIUS-1 payload in the Einstein-Elevator at the Leibniz University Hannover to create quantum bubbles. It will also contribute to efforts in testing and refining techniques for the Cold Atom Laboratory aboard the ISS. A primary goal is optimizing antenna designs and selecting radiofrequency sources to enhance magnetic field homogeneity, ensuring effective trapping in bubble configurations.
