Apparatus for quantum-mixture research in microgravity

Baptist Piest, Jonas Böhm, Timothé Estrampes, Priyanka Guggilam et autres

Abstract Experiments with ultracold quantum gases are a rapidly advancing research field with many applications in fundamental physics and quantum technology. Here, we report on a high-flux generation of Bose-Einstein condensate mixtures of 41 K and 87 Rb, using a fully integrated …

Dark energy search by atom interferometry in the Einstein-elevator

Charles Garcion, Sukhjovan S. Gill, Magdalena Misslisch, Alexander M. Heidt et autres

Abstract The DESIRE project aims to test chameleon field theories as potential candidates for dark energy. The chameleon field is a light scalar field that is subject to screening mechanisms in dense environments making them hardly detectable. The project is designed to …

Efficient numerical description of the dynamics of interacting multispecies quantum gases

Annie Pichery, Matthias Meister, Baptist Piest, Jonas Böhm et autres

We present a highly efficient method for the numerical solution of coupled Gross–Pitaevskii equations describing the evolution dynamics of a multi-species mixture of Bose–Einstein condensates in time-dependent potentials. This method, based on a moving and expanding reference frame, compares favorably to a …
