TL;DR: The AEGIS experiment at CERN/AD as mentioned in this paper was the first experiment to directly measure the Earth's gravitational acceleration on antihydrogen with a classical Moire deflectometer.
Journal ArticleDOI
Demonstration of three-dimensional electrostatic trapping of state-selected Rydberg atoms.
S. D. Hogan,Frédéric Merkt +1 more
TL;DR: The motion of the cold Rydberg atom cloud in the trap and the decay of the trapped atoms have been studied by pulsed electric field ionization and imaging techniques.
Journal ArticleDOI
Rydberg-state-enabled deceleration and trapping of cold molecules.
TL;DR: Hydrogen molecules in selected core-nonpenetrating Rydberg-Stark states have been decelerated from a mean initial velocity of 500 m/s to zero velocity in the laboratory frame and loaded into a three-dimensional electrostatic trap.
Journal ArticleDOI
Driving Rydberg-Rydberg transitions from a coplanar microwave waveguide.
TL;DR: Inhomogeneous, stray electric fields emanating from the surface of the waveguide have been characterized in frequency- and time-resolved measurements and coherence times of the Rydberg atoms on the order of 250 ns have been determined.
Journal ArticleDOI
Zeeman deceleration of H and D
TL;DR: In this article, a multistage Zeeman decelerator was used to accelerate hydrogen and deuterium atoms in supersonic jet expansion, and the phase-space distribution of the decelerated atoms was analyzed.
