Bragg-diffraction-induced imperfections of the signal in retroreflective atom interferometers
Jens Jenewein, Sabrina Hartmann, Albert Roura +1
We present a detailed study of the effects of imperfect atom-optical manipulation in Bragg-based light-pulse atom interferometers. Off-resonant higher-order diffraction leads to po…
Measuring gravitational time dilation with delocalized quantum superpositions
Albert Roura, Christian Schubert, Dennis Schlippert +1
Atomic clocks can measure the gravitational redshift predicted by general relativity with great accuracy and for height differences as little as 1 cm. All existing experiments, how…
Technologies for the ELGAR large scale atom interferometer array
B. Canuel, S. Abend, P. Amaro-Seoane +56
We proposed the European Laboratory for Gravitation and Atom-interferometric Research (ELGAR), an array of atom gradiometers aimed at studying space-time and gravitation with the p…
Atom interferometry and its applications
Sven Abend, Matthias Gersemann, Christian Schubert +7
We provide an introduction into the field of atom optics and review our work on interferometry with cold atoms, and in particular with Bose-Einstein condensates. Here we emphasize…
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…
Gravitational redshift in quantum-clock interferometry
Albert Roura
The creation of delocalized coherent superpositions of quantum systems experiencing different relativistic effects is an important milestone in future research at the interface of…
