Stratégie d'établissement

Nuclear physics is concerned with understanding the properties of atomic nuclei and nuclear matter in heavy ion collisions and compact stars. Theoretical physics and numerical modeling activities play a leading role and make very important contributions to the improvement of our knowledge of the complex properties of atomic nuclei. This numerical contribution is more and more essential today, for the understanding of nuclear matter under extreme conditions and of exotic systems located at the limits of existence in nature;in a context where projects for new facilities for nuclear physics have just been proposed or are under construction, for example the SPIRAL2 project of our national facility GANIL. A key aspect of the research at IN2P3 is to establish the link between the infinitely small and the infinitely large. Thus, advances in nuclear physics in the laboratory are used in particular in the context of nuclear astrophysics and the simulation of nuclear processes in stars and other celestial objects. The discovery of gravitational waves and the information obtained from their study feed into the determination of the equation of state of neutron stars. They therefore constitute special bridges between nuclear physics and astrophysics. Beyond this specific phenomenon, the simulation of complex objects and processes are subjects that the Institute wishes to enrich. These aspects have been detailed and are part of the recommendations of the working group "Nuclear physics and astrophysics" of the recent national perspectives in nuclear physics, particle and astroparticle physics.

Stratégie du laboratoire d'accueil

L2IT (Laboratoire des 2 Infinis - Toulouse) is a young laboratory created in 2020. The objects of study of the researchers and engineers at L2IT are the two infinities - the infinitely large and the infinitely small - and the phenomena that govern each of them, as well as the links between the two. Examples include the study of the Higgs boson and its role in the evolution of the Universe, or the emission of gravitational waves and their propagation in the Universe. The specificity of L2IT is its specialization in modeling, simulation and analysis. In this field, nuclear physics poses a particular challenge: the modeling of complex processes that take place inside nuclei - which are N-body quantum systems. Neutron stars are an extreme form of nuclear matter. Understanding them, based on the study of nuclear interactions in the laboratory, is another challenge. The person recruited will develop research on these subjects, which are new to the laboratory, in order to set up and lead a dedicated research pole. The Toulouse site has a rich activity on astrophysics and on the study of the emission of gravitational waves by compact objects such as neutron stars. The new chair will establish strong links while bringing an angle of investigation and research that is specific to the laboratory.

Stratégie Internationale

The last decade has been rich in results in nuclear physics. These results have triggered major efforts around the world to pursue the race to produce exotic nuclei in the laboratory, including Europe, the United States, China, South Korea, and Russia, demonstrating the enthusiasm for future discoveries to solve the fundamental scientific questions underlying nuclear astrophysics. The participation of theorists is essential in this quest. French theorists in nuclear physics are highly recognized internationally, have numerous collaborations and have trained and are training many students who go abroad to continue their research activities with postdoctoral contracts in prestigious laboratories and universities. The candidate will exchange and collaborate with theorists from other French laboratories and from other countries and will give L2IT a great international visibility.

Résumé du projet scientifique

Nuclear physics today not only aims at an understanding of the most complex processes within nuclei from fundamental principles, but also uses the knowledge acquired to describe the processes at work in extreme systems, such as astrophysical objects, an example of which are neutron stars. More and more sophisticated models in their formal and numerical aspects are developed today for the treatment of the nuclear N-body problem. Important efforts are also devoted to the understanding and construction of the nuclear interaction based on a completely microscopic basis, for its use in so-called 'ab-initio' approaches. The development of highly complex models for atomic nuclei and studies of the nuclear interaction make an essential and unique contribution to the improvement of our knowledge of nuclear structure and reactions, as well as to the description of objects of interest in nuclear astrophysics. For example, this research has an impact on the development of models of nucleosynthesis and on the formulation of the equation of state of nuclear matter. The skills required are formal and numerical skills for the theoretical modeling of nuclear N-body systems.

Résumé du projet d'enseignement

At the Faculty of Sciences and Engineering at the University of Toulouse III, the vast majority of the teaching hours provided are in the Bachelor's degree program. In physics, the emphasis is on fundamental skills (notably mechanics, electromagnetism, optics) as well as on advanced scientific analysis tools (notably mathematical tools and numerical tools). The person recruited will contribute to the teaching of these disciplines at the undergraduate level. A good knowledge of mechanics and electromagnetism is essential for any study of subatomic physics. The development of new algorithms for data analysis and numerical simulations is the specificity of L2IT, and mathematical and numerical tools are at the heart of our research work. Contributing to these courses is particularly motivating for us and allows us to make students aware of our research fields. The person recruited will contribute to the teaching of subatomic physics (analysis methods, statistics, nuclear physics) in the new option on this theme which is created in the PEnTE master from the academic year 2022/23.

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.
The results in theoretical nuclear physics as well as the numerical simulation methods developed in the framework of this project will be presented at dedicated conferences and published in scientific journals in the field. Two prestigious and recurrent international conferences in nuclear physics are for example INPC (International Nuclear Physics Conference) or ARIS (Advances in Radioactive Isotope Science), where theorists are used to presenting their work. French theorists also often organize (and participate in) workshops at ECT* Trento (European Centre for Theoretical Nuclear Physics and Related Areas), in Italy, and at the INT (Institute for Nuclear Theory) in Seattle, USA. At the national level, results will be disseminated in the GDR RESANET ("Reactions, Structure and Nuclear Astrophysics: Experiments and Theories") and NBODY ("N-body Quantum Problem in Chemistry and Physics"), recognized interdisciplinary meeting points of the community. Presentations at the very prestigious CHEP (International Conference on Computing in High Energy & Nuclear Physics) conference series and publications in the journal Computing and Software for Big Science will be targeted .

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.
This project is based on both nuclear physics and data science, and both sciences have a well-established open science culture. The publication of algorithms is a widespread practice and a driver of progress in data science. This project naturally embraces this established culture and will make public the methods and algorithms developed. Publications will be systematically deposited in accessible archives such as arXiv.

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 .
In addition, the project will implement a communication towards various targets such as scientific communities, media, decision-makers, general public, schools, etc., with an adapted calendar.

This project will make a particular effort to nurture the interest of the society in its work. This effort will naturally involve contributions to events for the general public that are regularly organized (Science en Fête, Nuit des Chercheurs, ...), but also specific actions such as writing articles for the general public. The members of L2IT are proud of the large fraction of women in its teams;in particular in the fields of engineering, computer science and data science. The creation of the Laboratoire des 2 Infinis - Toulouse and its specificity (innovative analysis methods) are the subject of an article in the magazine Sciences et Avenir. This project will make an effort to expose the richness and professional perspectives of these fields to young girls .
