Beyond Born-Oppenheimer approximation in ultracold atomic collisions

Eberhard Tiemann, Philipp Gersema, Kai K. Voges +3

We report on deviations beyond the Born-Oppenheimer approximation in the potassium inter-atomic potentials. Identifying three up-to-now unknown -wave Feshbach resonances, we sig…

The Bose-Einstein Condensate and Cold Atom Laboratory

Kai Frye, Sven Abend, Wolfgang Bartosch +48

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

Elementary laser-less quantum logic operations with (anti-)protons in Penning traps

Diana Nitzschke, Marius Schulte, Malte Niemann +5

Static magnetic field gradients superimposed on the electromagnetic trapping potential of a Penning trap can be used to implement laser-less spin-motion couplings that allow the re…

Gouy's Phase Anomaly in Electron Waves Produced by Strong-Field Ionization

Simon Brennecke, Nicolas Eicke, Manfred Lein

Ionization of atoms by linearly polarized strong laser fields produces cylindrically symmetric photoelectron momentum distributions that exhibit modulations due to the interference…

ELGAR -- a European Laboratory for Gravitation and Atom-interferometric Research

B. Canuel, S. Abend, P. Amaro-Seoane +55

Gravitational Waves (GWs) were observed for the first time in 2015, one century after Einstein predicted their existence. There is now growing interest to extend the detection band…

Kinematically complete experimental study of Compton scattering at helium atoms near the ionization threshold

Max Kircher, Florian Trinter, Sven Grundmann +15

Compton scattering is one of the fundamental interaction processes of light with matter. Already upon its discovery [1] it was described as a billiard-type collision of a photon ki…
