Probing quantum physics with correlated atomic pairs – ProQuP

Submission summary

Two partners are involved in this project, both being pioneering groups in quantum atom optics and one-dimensional quantum gases: the laboratoire Charles Fabry de l’Institut d’Optique (Institut d’Optique, CNRS, Université Paris Sud 11) through the setups « metastable helium » et « atom chip », and the Atominstitut der Österreichischen Universitäten (Vienna University of Technology) through one setup on « atom chip ».
Strongly correlated states are at the heart of the project. These states are expected to increase the sensitivity in atomic interferometry and are central to understand 1D physics.
The project could be split in three main parts. The first one deals with the search of an efficient process of twin atomic beams. Their quantum properties will be studied through two-body correlation function, an asset of the two partners since both have developed state of the art single atom detectors. Two-mode source will be particularly studied.
The second part is linked to 1D physics. In particular the integrability of such atomic systems will be studied et their two-body correlation function during time-of-flight and in-situ will be measured. This last point will be achieved by a new method based on tomography.
The third part concerns a transfer of technology. The Austrian partner will help the French partner to build a single atom, time-resolved, light-sheet detector similar to the one developed in Austria.
