Atom interferometers covering macroscopic domains of space-time are a spectacular manifestation the wave nature matter. Because their unique coherence properties, Bose-Einstein condensates ideal sources for an atom interferometer in extended free fall. In this Letter we report on realization asymmetric Mach-Zehnder operated with condensate microgravity. The resulting interference pattern is similar to one far field double slit and shows linear scaling time packets expand. We employ...
Albert Einstein's insight that it is impossible to distinguish a local experiment in "freely falling elevator" from one free space led the development of theory general relativity. The wave nature matter manifests itself striking way Bose-Einstein condensates, where millions atoms lose their identity and can be described by single macroscopic function. We combine these two topics report preparation observation condensate during fall 146-meter-tall evacuated drop tower. During expansion over...
The theory of general relativity describes macroscopic phenomena driven by the influence gravity while quantum mechanics brilliantly accounts for microscopic effects.Despite their tremendous individual success, a complete unification fundamental interactions is missing and remains one most challenging important quests in modern theoretical physics.The STE-QUEST satellite mission, proposed as medium-size mission within Cosmic Vision program European Space Agency (ESA), aims testing with high...
Advances in quantum technologies are giving rise to a revolution the way fundamental physics questions explored at empirical level.

Microgravity eases several constraints limiting experiments with ultracold and condensed atoms on ground. It enables extended times of flight without suspension eliminates the gravitational sag for trapped atoms. These advantages motivated numerous initiatives to adapt operate experimental setups microgravity platforms.

Recent developments in quantum technology have resulted a new generation of sensors for measuring inertial quantities, such as acceleration and rotation. These can exhibit unprecedented sensitivity accuracy when operated space, where the free-fall interrogation time be extended at will environment noise is minimal. European laboratories played leading role this field by developing concepts tools to operate these relevant environment, parabolic flights, towers, or sounding rockets. With...
Modern material handling systems (MHS) are complex which controlled by various control units on different automation levels. The design of the MHS facility layout and development require application CAE tools but simulation virtual commissioning does currently not play a significant role because there is no integrated simulation-based verification environment for all project stages levels available. This paper presents an approach towards tool project. During first stage flow plant model...

Bose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne matter-wave interferometry. Indeed, BECs enjoy slowly expanding wave function, display large spatial coherence and can be engineered probed by optical techniques. On sounding rocket, we explore fringes of multiple spinor components BEC released employing light-pulses to drive Bragg processes induce phase imprinting. The prevailing microgravity played crucial role the observation these interferences...
