GRAVITY+ Wavefront Sensors: High-Contrast, Laser Guide Star, Adaptive Optics systems for the VLTI
G. Bourdarot, F. Eisenhauer, S. Yazıcı +53
We present the Wavefront Sensor units of the Gravity Plus Adaptive Optics (GPAO) system, which will equip all 8m class telescopes of the VLTI and is an instrumental part of the GRA…
A simple method for generating Bose-Einstein condensates in a weak hybrid trap
M. Zaiser, J. Hartwig, D. Schlippert +5
We report on a simple novel trapping scheme for the generation of Bose-Einstein condensates of Rb atoms. This scheme employs a near-infrared single beam optical dipole trap…
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…
Quantum test of the Universality of Free Fall using rubidium and potassium
H. Albers, A. Herbst, L. L. Richardson +11
We report on an improved test of the Universality of Free Fall using a rubidium-potassium dual-species matter wave interferometer. We describe our apparatus and detail challenges a…
Irreducible completely pointed modules of quantum groups of type
V. Futorny, J. Hartwig, E. Wilson
We give a classification of all irreducible completely pointed modules over a characteristic zero field in which is not a root of unity. This general…
Ground Tests of Einstein's Equivalence Principle: From Lab-based to 10-m Atomic Fountains
D. Schlippert, H. Albers, L. L. Richardson +10
To date, no framework combining quantum field theory and general relativity and hence unifying all four fundamental interactions, exists. Violations of the Einstein's equivalence p…
