Quantum mechanics governs the microscopic world, where low mass and momentum reveal
a natural wave–particle duality. Magnifying quantum behaviour to macroscopic scales is a …

In contrast to light, matter-wave optics of quantum gases deals with interactions even in free
space and for ensembles comprising millions of atoms. We exploit these interactions in a …

The capability to reach ultracold atomic temperatures in compact instruments has recently
been extended into space,. Ultracold temperatures amplify quantum effects, whereas free …

We report the status of the Cold Atom Lab (CAL) instrument to be operated aboard the
International Space Station (ISS). Utilizing a compact atom chip-based system to create …

Microgravity eases several constraints limiting experiments with ultracold and condensed
atoms on ground. It enables extended times of flight without suspension and eliminates the …

We present the design of a compact absolute optical frequency reference for space
applications based on hyperfine transitions in molecular iodine with a targeted fractional …

We present measurements of interspecies Feshbach resonances and subsequent creation
of dual-species Bose-Einstein condensates of Na 23 and K 39. We prepare both optically …

Abstract The Cold Atom Laboratory on the International Space Station produces ultracold
gases of rubidium and potassium in a tight magnetic trap near the surface of a magnetic …

In the vicinity of a narrow Feshbach resonance Efimov features are expected to be
characterized by the resonance's properties rather than the van der Waals length of the …

We study enhanced magneto-association of atoms into weakly bound molecules near a
Feshbach resonance using a quench preparatory stage. In anticipation of experiments with …
