Research at the Physics Graduate School

Research in Physics is carried out by more than 3,000 researchers, engineers and technicians in some forty laboratories on the Paris-Saclay campus. It brings together a very wide range of scientific and technical professions and expertise. It is carried out within multiple collaborations, in the broader Paris area, nationally, Europe-wide or worldwide, and gives rise to numerous synergies with the local and national industrial network. One of the specific features of Physics at Université Paris-Saclay also lies in the number and diversity of platforms and major research instruments at the cutting edge of what is being done in the world, and which enjoy a very high national and international visibility. Locally, these research centres participate in the training of a thousand master's and doctoral students.

Research in Physics at Université Paris-Saclay is organised into three thematic pillars: Physics of Waves & Matter (PhOM: Physique des Ondes et de la Matière), Physics of the 2 Infinities (P2I: Physique des 2 Infinis), Astrophysics.

Physics of Waves & Matter (PhOM)

This involves the study, description, and application of the principles and phenomena of physics at scales ranging from the atom to the planet, as well as the emergence of complexity in systems with (very) numerous components, governed by multiple interactions in cooperation or competition. It includes the fields of extreme light, the physics of neutral or ionised dilute media (including atomic physics, molecular physics, and plasma physics), nanophysics, growth and properties of materials, the physics of quantum coherence and correlations (including quantum materials and topology effects), quantum entanglement and technologies, optics and photonics, complex systems and matter. PhOM teams lead research programmes in fundamental and applied physics, experimental as well as theoretical, within their disciplinary field as well as in the broad interdisciplinary context.

Physique of the 2 Infinities (P2I)

Major questions concern the ultimate and infinitely small components of matter and the fundamental laws governing their interactions, the origin and evolution of the infinitely large components of the Universe, the strong interaction, the emergence of complexity, and the origin of elements in the Universe. Specific fields include particle physics, nuclear physics, astroparticle physics, cosmology, theoretical physics, energy (including nuclear reactor physics) and health. P2I teams are members of the very large, internationally recognised research infrastructures. They possess a unique know-how in cutting-edge technologies and also conduct original interdisciplinary research on societal issues (in particular health and energy).

Major questions concern the way the solar system works, the formation and evolution of stars and planetary systems, the formation and evolution of large structures, and the physics under extreme conditions. Specific fields include cosmology, galaxies, high energies, the interstellar medium, extraterrestrial matter, star formation, planetary sciences, solar and stellar physics, astrophysical plasmas. The main methods used are ground and space instrumentation (in the broadest sense, including all phases from the design of detectors and observation instruments to their astrophysical exploitation), data and signal science, numerical simulations, and theory.
