Missions

The candidate will coordinate the activities carried out by the team within the framework of a new project called “CoQuIA” (Quantum Control for Atomic Interferometry) funded by AID. He or she will work on both the experimental and theoretical study of methods of shaping laser beams of atomic interferometers, based on the use of unconventional optical elements and optimal quantum control methods. He or she will coordinate the implementation of these new methods in the laboratory, in collaboration with the students working on the different experimental devices. He or she will prepare the experimental plans, participate in the analysis of the results, which he or she will present in the project progress meetings and in conferences in the field. He or she will write the progress reports, as well as the publications resulting from his research.

Activities

On a theoretical level, he or she will continue the development already started in the team of numerical codes for optimal control based on gradient methods. Experimentally, he or she will use a test bench to test different methods of rapid modulation of pulse parameters (phase / frequency, amplitude). Once the methodology is validated, on the theoretical and experimental levels, he or she will implement these methods in inertial sensors at the state of the art, and in particular in an atomic gyrometer of very large area and an atomic gradiometer of very high sensitivity, both operational today, with the objective of improving the efficiency of light beamsplitters, the contrast of interferometers and therefore ultimately the sensitivity of the measurements of rotation speed and gravity gradient. He or she will perform the comparison between the results obtained and the numerical simulations.

Skills

The candidate should hold a PhD degree in physics and have strong experimental skills in laser physics, atomic physics, electronics and instrument control. Research experience in the field of cold atoms is mandatory. Any experience in the field of atomic interferometry will be highly appreciated. An expertise and a taste for numerical simulations will be an asset.

Work Context

The researcher will join the “Atomic interferometry and inertial sensors” team at SYRTE, a leading laboratory in the development of high sensitivity inertial sensors based on atomic interferometry, such as gravimeters and gyrometers, using trapped cold atoms or in free fall. He or she will work under the direction of Franck Pereira dos Santos, Director of Research at CNRS, team leader at SYRTE and coordinator of the CoQuIA project. He or she will collaborate closely with the teams involved in the development of the instruments.
