Job Description
Missions
The project focuses on the manipulation of matter waves using modulated light potentials in two types of inertial sensors based on atomic interferometry. A primary area of study will focus on the use of optical “lenses” for free-falling matter waves, utilizing dipolar laser pulses to enhance interactions and induce spin compression—that is, 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 realized using a sequence of Raman pulses, and should make it possible to reduce measurement noise below the standard quantum limit. A second line of research will focus on the construction of interferometers using atoms trapped in an optical lattice, where the optical beamsplitters will be created by modulating the lattice parameters. The objective will be to optimize the efficiency of the beamsplitters and to study the evolution of the interferometer's contrast and phase as a function of the separation between the wave packets.
Activity
- Optimization of the Bose-Einstein condensate preparation sequence using painted potentials, increasing the number of condensed atoms
- Implementation of lenses in the interferometer
- Measurements of population fluctuations at the output of an interferometer below the quantum limit
- Implementation of modulation profiles obtained via optimal control
- Study of sources of coherence loss in a trapped interferometer
Your Profil
Skills
Experimental expertise in atomic interferometry, cold atoms, and metrology
Your Work Environment
-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 setup that is currently operational.
The position falls within a sector subject to scientific and technical security (PPST) regulations and therefore requires, in accordance with the regulations, authorization from the competent authority at the MESR.
