STE-QUEST - Test of the Universality of Free Fall Using Cold Atom Interferometry
D. Aguilera, H. Ahlers, B. Battelier +63
The theory of general relativity describes macroscopic phenomena driven by the influence of gravity while quantum mechanics brilliantly accounts for microscopic effects. Despite th…
Interferometry with Bose-Einstein Condensates in Microgravity
H. Müntinga, H. Ahlers, M. Krutzik +41
Atom interferometers covering macroscopic domains of space-time are a spectacular manifestation of the wave nature of matter. Due to their unique coherence properties, Bose-Einstei…
Efficient Guiding of Cold Atoms though a Photonic Band Gap Fiber
S. Vorrath, S. A. Möller, P. Windpassinger +2
We demonstrate the first guiding of cold atoms through a 88 mm long piece of photonic band gap fiber. The guiding potential is created by a far-off resonance dipole trap propagatin…
MACOR glass-ceramic based UHV cell for quantum technology applications
M. Proske, S. Boles-Herresthal, D. Latorre-Bastidas +6
Compact, customizable, non-magnetic vacuum systems are a key requirement for many field applications of quantum technology based on cold atoms. We report on the development and con…
Cooperative effects in dense cold atomic gases including magnetic dipole interactions
N. S. Bassler, I. Varma, M. Proske +3
We theoretically investigate cooperative effects in cold atomic gases exhibiting both electric and magnetic dipole-dipole interactions, such as occurring for example in clouds of d…
A compact and robust diode laser system for atom interferometry on a sounding rocket
V. Schkolnik, O. Hellmig, A. Wenzlawski +9
We present a diode laser system optimized for laser cooling and atom interferometry with ultra-cold rubidium atoms aboard sounding rockets as an important milestone towards space-b…
Trapping of Neutral Rubidium with a Macroscopic Three-Phase Electric Trap
T. Rieger, P. Windpassinger, S. A. Rangwala +2
We trap neutral ground-state rubidium atoms in a macroscopic trap based on purely electric fields. For this, three electrostatic field configurations are alternated in a periodic m…
