Stratégie d'établissement

Pushing the sensitivity of low-energy experiments to the extreme in order to explore the fundamental laws of the Universe and test the Standard Model is fully in line, directly or indirectly, with several research priorities of the CNRS's 2019-2023 Contract of Objectives and Performance: 2.1. 8 (Quantum matter, information and technologies), 2.2.3 (Understanding matter-antimatter asymmetry), 2.2.4 (Understanding the fundamental laws of the Universe), 2.4.1 (Observing the Universe), 2.4.2 (Discovering the nature of dark matter), and 2.4.3 (Understanding the dynamics of the Earth's fluid envelopes).
The PRECISION junior professor chair aims to attract a talented researcher capable of designing and leading a project at the cutting edge of experimental research. This project will draw on the unique properties of ultra-cold atoms and molecules, trapped ions, as well as recent advances in quantum control and atom interferometry. These approaches, far from being exclusive, could be combined to push back the limits of precision in experimental measurements even further.
The candidate will have complete liberty to propose an ambitious project, with applications to tests of fundamental physics and aimed at exploring the frontiers of the Standard Model. Possible topics include, but are not limited to, the determination or study of the possible variation of fundamental constants, the investigation of fundamental symmetries, the measurement of the electron's electric dipole moment, and the development of cutting-edge technologies to improve the sensitivity of atom interferometers. These advances could open up promising prospects for the design of a gravitational wave detector based on atom interferometry.

Stratégie du laboratoire d'accueil

The LAC is recognized as one of the world leaders in the field of cold molecules, with world-class results in both theory and experiment. In recent years, it has forged excellent international collaborations, notably with the University of Hanover, Harvard, the JILA and Hong Kong.
The LKB is one of the major actors in quantum physics. It is renowned for its expertise in quantum metrology, atom interferometry and high-resolution spectroscopy of simple, exotic and trapped ion systems. The LKB participates in large-scale programmes and international collaborations such as GBAR and LIGO-Virgo.
The LPL has recognised expertise in frequency metrology, ultra-precise spectroscopy and molecular cooling. With the REFIMEVE infrastructure, the LPL is equipped with ultrastable lasers to probe molecular resonances with high precision and has carried out several fundamental tests at the international state-of-the art.

Stratégie Internationale

The international policy of CNRS Physics aims to enhance the impact and relevance of its research by fostering collaborations with research teams from around the world. Numerous European projects in the field of trapped ions and cold molecules focus on the dissemination of metrological signals, coordinated in part by the LPL (REFIMEVE network). A new European project, “Fundamental Physical Metrology with Cold Molecules,” involving the LPL, has just been funded.
For many years, the LPL and LAC have developed a unique network of international collaborations with chemists and physicists specializing in the modeling of molecular interactions to guide experimental work. Similarly, the LKB has extensive expertise in quantum electrodynamics calculations. There is a large international community dedicated to atom interferometry, and the field of long-baseline matter-wave sensors is currently experiencing rapid growth.
To attract top candidates, the laboratories will rely on a number of European and international networks, such as the COST network AtomQTech, the international TLVBAI network (Terrestrial Very-Long-Baseline Atom Interferometry), and the European ELGAR initiative, supported by CNRS.

Résumé du projet scientifique

Applicants are expected to propose an ambitious project at the forefront of experimental research. The project should leverage the unique properties of ultracold atoms and molecules, trapped ions, as well as recent advances in quantum control and atomic interferometry. These approaches, which are not exclusive, can be combined to further push the limits of precision in experimental measurements. Research topics may include, but are not limited to: the determination and investigation of possible variations in fundamental constants, the study of fundamental symmetries, the measurement of the electron's electric dipole moment, the testing of alternative theories, including those aiming to unify quantum mechanics and gravity, and the development of cutting-edge technologies for large-scale atom interferometers, paving the way for reaching the sensitivity required to detect gravitational waves.

Résumé du projet d'enseignement

Applicants are expected to propose a teaching project (equivalent to 28 hours of lectures or 42 hours of practical or tutorial sessions) related to the theme of the junior professor chair "PRECISION." The topics are broad and may cover both fundamental aspects—such as quantum control of atomic and molecular systems—and technical aspects, such as the study and control of noise sources or laser frequency stabilization techniques.
The proposed teaching project will then be discussed and finalized in coordination with the academic institutions affiliated with the host laboratory of the selected candidate.

Diffusion scientifique

The dissemination of the results will be done through world-class scientific productions: publications, patents, software... In addition, the results will be communicated to various targets such as scientific communities, media, decision makers, general public, schools, etc., with an adapted calendar. Specific tools may be developed such as websites, newsletters, meetings, international symposia, summer schools and conferences.

Science ouverte

The CNRS is developing a strong policy in favor of open science. Open science consists of making research results "as accessible as possible and closed as necessary". As such, the CNRS aims to make 100% of the texts of publications resulting from the work of its laboratories accessible , in particular through deposit in HAL. The data produced must also be made available and reusable, except for specific restrictions. In addition, the guiding principles of individual evaluation have been revised in accordance with the DORA declaration, to be more qualitative and to take into account all facets of the researcher's profession.

Science et société

The relationship between science and society is now recognized as a full dimension of scientific activity. The project will develop this dimension in synergy with all the partners. The resulting research work will contribute to informing public decision-making. Participatory science initiatives may be initiated with actors from the project's socio-economic and cultural eco-system.

Indicateurs

The activity will be evaluated in particular on the basis of scientific production (publications, software, patents, etc.), on institutional and private partnerships formalized by contracts, on international presence, on the promotion of work to multidisciplinary scientific communities, on innovation and its transfer to society and on scientific dissemination to non-specialist audiences.
