Context and objectives of the project. Cold atom interferometers have reached levels of sensitivity and precision competing with or surpassing inertial sensors based on different technologies. These sensors have several applications in geophysics, inertial detection, metrology and fundamental physics. The widening of their field of application requires to push constantly further their performances in terms of sensitivity, stability, precision, dynamic range, compactness or robustness, ease of use and cost. More than 40 research groups around the world are actively developing inertial cold atom sensors for different applications, and are studying techniques to improve their performance.
The project will be carried out on the experiment of the cold atom gyroscope-accelerometer of the IACI group, which has repeatedly demonstrated record performances. The first stage of this project will consist in using the experiment to carry out a special relativity test (Sagnac effect for matter waves) in a range of precision still unexplored, in collaboration with the theoretical team of the laboratory. The postdoctoral researcher will then work progressively on the development of a new experiment of gyroscope with ultra-cold atoms with two axes which reaches a stability of 1 prad / s for the rotation measurements, which represents an improvement of two orders of magnitude compared at the current level. This level of exquisite sensitivity will make it possible to carry out rotation rate measurements of great interest for the rapidly expanding field of rotational seismology. The researcher will also participate in the use of this instrument for a test of gravitational decoherence models by atomic interferometry.
Profile of the applicant. We are looking for exceptional candidates strongly motivated by stimulating experimental physics projects, preferably with a PhD experience in atomic physics (ideally in atomic interferometry) and instrumentation skills. The postdoctoral researcher is expected to work in a team and will gradually be responsible for daily management (for example, providing advice to students), while being involved in scientific and strategic decisions concerning the project. The researcher will also be invited to write research proposals in order to gain autonomy and improve his career (for example, Marie Curie applications).
Future career development. The IACI team has a good track record in the employment of postdoctoral researchers, whether in the university or industrial sector. Applications for permanent positions in the laboratory will be encouraged.
Conditions. The position is based on a full-time job at the SYRTE laboratory, with a salary according to experience. It is funded for at least 18 months as part of the "Inertial Precision Measures by Atomic Interferometry" project of the National Research Agency (ANR). The position is associated with the normal social security system provided for in France (for example, health insurance). Assistance in finding accommodation and settling in Paris will be provided.
The laboratory and the team. The SYRTE laboratory, located on the Paris Observatory campus, is a joint research unit of the CNRS, the University of the Sorbonne and the National Metrology Laboratory (LNE). It is an interdisciplinary laboratory specializing in time and frequency metrology, atomic interferometry, astronomy for the definition of celestial reference frames and the history of science, which enjoys an international reputation in these fields. The Atomic Interferometry and Inertial Sensors group (IACI) (twenty researchers) has been developing the field of cold atom inertial sensors for 20 years and is recognized worldwide for its expertise in this field, both in fundamental applications and in the field of interferometers atomic. In addition to the pioneering fundamental studies, the team is ready to create links with the industry, a striking example being the creation in 2011 of the spin-off company muQuans. The team has solid international collaborations and is integrated into the SIRTEQ network of quantum technology in the Paris region.
