Missions

The proposed project involves the experimental implementation of a new method for manipulating atomic wave packets, based on the use of optical “lenses” for matter waves, using dipole laser pulses. Focusing the matter waves will enhance the effects of interactions and induce spin compression, i.e., a reduction in the quantum fluctuations associated with the collective state of the atoms. The atoms manipulated in this way will serve as sources for an atomic interferometer built using a sequence of Raman pulses, and should make it possible to reduce measurement noise below the standard quantum limit.

Contexte de travail

The postdoctoral researcher will join the “Atomic Interferometry and Inertial Sensors” team at LTE, a leading laboratory in the development of high-sensitivity inertial sensors based on atomic interferometry, such as gravimeters and gyrometers, using trapped or free-falling cold atoms. He or she will work under the supervision of Franck Pereira dos Santos, Research Director at the CNRS and team leader at the LTE, on an experimental device that is currently operational.
