Apparatus for quantum-mixture research in microgravity
Baptist Piest, Jonas Böhm, Timothé Estrampes +24
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…
Additively manufactured ceramics for compact quantum technologies
Marc Christ, Conrad Zimmermann, Sascha Neinert +3
Quantum technologies are advancing from fundamental research in specialized laboratories to practical applications in the field, driving the demand for robust, scalable, and reprod…
A Dual-Species Atom Interferometer Payload for Operation on Sounding Rockets
Michael Elsen, Baptist Piest, Fabian Adam +36
We report on the design and the construction of a sounding rocket payload capable of performing atom interferometry with Bose-Einstein condensates of K and Rb. The ap…
A single-laser alternating-frequency magneto-optical trap
B. Wiegand, B. Leykauf, K. Döringshoff +3
In this paper, we present a technique for magneto-optical cooling and trapping of neutral atoms using a single laser. The alternating-frequency magneto-optical trap (AF-MOT) uses a…
JOKARUS - Design of a compact optical iodine frequency reference for a sounding rocket mission
Vladimir Schkolnik, Klaus Döringshoff, Franz Balthasar Gutsch +9
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 frequen…
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…
Macroscopic quantum resonators (MAQRO): 2015 Update
Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer +49
Do the laws of quantum physics still hold for macroscopic objects - this is at the heart of Schrödinger's cat paradox - or do gravitation or yet unknown effects set a limit for mas…
Ultra-stable cryogenic optical resonators for tests of fundamental physics
M. Nagel, K. Möhle, K. Döringshoff +3
We present the design and first measurement results for an ultra-stable cryogenically cooled optical sapphire resonator system with a potential relative frequency stability better…
Highly stable piezoelectrically tunable optical cavities
Katharina Möhle, Evgeny V. Kovalchuk, Klaus Döringshoff +2
We have implemented highly stable and tunable frequency references using optical high finesse cavities which incorporate a piezo actuator. As piezo material we used ceramic PZT, cr…
Electromagnetic cavity tests of Lorentz invariance on Earth and in space
M. Nagel, K. Möhle, K. Döringshoff +2
We present a Michelson-Morley type experiment for testing the isotropy of the speed of light in vacuum and matter. The experiment compares the resonance frequency of an actively ro…
Testing Lorentz Invariance by Comparing Light Propagation in Vacuum and Matter
M. Nagel, K. Möhle, K. Döringshoff +4
We present a Michelson-Morley type experiment for testing the isotropy of the speed of light in vacuum and matter. The experiment compares the resonance frequency of a monolithic o…
