Research at CNRS Physics focuses on the study of matter, radiation and the fundamental laws which govern the physical world. Physics has thematic diversity and seeks to reveal the main principles underlying the properties and behavior of objects, however complex these may be. Its approach also very much influences and nourishes research in other disciplines.
Research in physics focuses on understanding the mechanisms underlying the observable phenomena of matter and radiation and of their interactions. To achieve their goals, the CNRS Physics' teams carry out experiments, conduct theoretical work, model and numerically simulate phenomena. They design the instruments and tools necessary for their research and rely on the development of infrastructures and technological platforms, in particular very large research infrastructures (TGIRs), and work collectively to advance knowledge.
CNRS Physics' research takes place within a broad disciplinary field that covers fundamental interactions, electromagnetism, atoms, molecules, complex organized or disorganized matter, as well as optics. To carry out its primary mission of broadening the field of knowledge in its discipline, the INP focuses on six major strategic research areas:
The foundations of CNRS Physics' work lie in understanding the world around us. CNRS Physics develops constantly evolving disciplines which cover broad fields, ranging from elementary to complex phenomena. Its research overlaps with those of engineering, chemistry, biology, mathematics and sometimes the humanities and the social sciences. This can be seen in its many interfaces and projects run in synergy with other CNRS Institutes - with CNRS Nuclear and Particle Physics, CNRS Earth Sciences and Astronomy and CNRS Engineering and Systems Sciences for particle physics, cosmology, astrophysics and engineering, and also CNRS Mathematical Sciences, CNRS Chemistry and CNRS Biological Sciences. These links involve not only instruments and methods associated with theoretical or experimental approaches, but also software developed by physicists and transcribed or adapted for use in other fields of research.
The study and advanced characterization of matter and of all manifestations of its interactions, including the various levels and scales at which they operate, set many challenges for researchers. These systems include isolated atoms and molecules, plasmas, gases, liquids, amorphous or crystalline solids and biological systems. The tools developed, to help knowledge progress and to inspire new technologies, need to be particularly effective. Their aim is also to help answer questions posed by other disciplines (chemistry, biology, earth sciences, astrophysics, cosmology, engineering) through collaborations. These high-performance tools arise from a wide variety of instrumental developments, and range from laboratory tools to shared equipment (nanotechnology centers, electron microscopes, NMR, radiation sources), including large and very large research infrastructures. Networks of research platforms and infrastructures enable researchers to organize their work at the regional, national and European levels. The expensive advanced instruments developed and implemented in these networks are open to the scientific community via project calls and program committees suitable to each type of instrument. European-level organization and management strengthens the dynamics of international exchanges and the quality of instrument development.
Together with the other CNRS institutes and its partners outside the organization, the CNRS Physics participates actively in the steering bodies of many research infrastructures (IRs) and very large research infrastructures (TGIRs).

The research teams of CNRS Physics also work on - and use - supercomputers at national facilities such the Institute for Development and Resources in Intensive Scientific Computing (IDRIS) in Orsay, the Très Grand Centre de Calcul (TGCC) in Bruyère-le-Châtel, the Centre Informatique National de l’Enseignement Supérieur (CINES) in Montpellier, as well as at the international facilities managed by PRACE, but also on smaller computers in mid-sized, regional facilities.
The Research Networks (GDR) bring together and mobilize research teams from various disciplines, from different CNRS institutes, as well as academic or industrial stakeholders, around original or emerging scientific themes. This page lists the GDRs led by CNRS Physics and outlines their research areas.
A CNRS Research Networks (GDR) connects and unites a scientific community around an emerging, original theme. CNRS Physics initiates GDRs focused on scientific topics that address current fundamental or societal issues. These topics may fall within the core business but can also involve interfaces between physics and other scientific fields. In this respect, transdisciplinary GDR led by CNRS Physics are supported in collaboration with other relevant CNRS institutes.
The main missions of a GDR are to foster a thematic, often multidisciplinary, community; to encourage free access to new partners; to promote collaboration and exchange among scientists within the network of participating laboratories; and to establish scientific projects at national, European, or international levels. Expanding GDR communities to include industrial stakeholders—for instance, through the creation of a "partners' club"—enables mutual enrichment and the identification of shared research topics.
This page presents, in the form of summary sheets, the objectives of each Research Network led CNRS Physics. Beyond describing their research focuses, each summary offers the opportunity for new partners—possibly from other disciplinary fields or non-academic sectors—to contact the GDR and join their mailing lists.
The Horizon 2D and Heterostructures (2D+) research network is a horizontal research network that aims to bring together the French community working on two-dimensional materials and associated low-dimensional systems (van der Waals heterostructures, moiré patterns, twisted systems, nanotubes, 2D–1D and 1D–0D hybrids, etc.). Research topics cover synthesis, characterisation, theory and devices, addressing both fundamental properties and emerging functionalities. In a highly competitive international context, the GDR 2D+ promotes scientific exchange, interdisciplinarity, collaboration and visibility at national and international levels.

The Quantitative Approaches to Life Sciences (AQV) research network was created to consolidate and promote links between communities at the interface between biology and physics. The creation of the AQV GDR was based on two observations: (1) today, a better understanding of living organisms requires quantifying and modelling them and taking into account the laws of physics and chemistry, (2) this approach can only be implemented in an interdisciplinary framework. Beyond importing tools and concepts, it also involves addressing key questions in biology through approaches that combine biology and physics. These advances enable the development of new physical concepts (examples: active matter, physics far from equilibrium, noise robustness, learning in frustrated systems, dynamics of very high-dimensional systems).
