Variable renewable energies such as wind and solar power are expected to become the main contributors to the world's power systems as a large number of countries, including France, set ambitious targets to achieve carbon neutrality.In a long-awaited joint report commissioned by the Ministry of …

"Currently, most language generation algorithms are based on deterministic neural networks, resulting in word sequence decoding mechanisms that produce either degenerate or simplified and overly generic language." This is the problem that guides the work of Alice Martin, a young researche…

Launched by the SNCF group, the École polytechnique and the Fondation de l'École polytechnique, this new teaching and research chair will develop innovative AI-based technologies to improve the quality and sustainability of transport. It will involve Polytechnique engineering students in the challe…

Developed within the EuroTeQ Engineering University project, an innovative learning format enters École Polytechnique’s course catalog and brings students, faculty, and industry partners together around concrete environmental challenges.

École Polytechnique is continuing to adapt its historic curriculum, the ingénieur polytechnicien program, to contemporary societal and sovereignty issues. A new course entitled “Global Equilibria, Sovereignty and Defense Issues” for 1st year students began on April 18, 2024.

At the Laboratory of Condensed Matter for Physics (PMC*), a team has successfully determined the spin-dependent electronic structure linked to the presence of defects in the arrangement of atoms in a semiconductor. This is the first time that this structure has been measured. The results are publis…

How to monitor continuously but without disturbing them charged particle beams like those used in proton therapy? By interposing as little material as possible! These are 1.5 micrometers (0.00015cm) membranes on which strips of 50 nanometers are deposited which form the new ultra-thin monitor devel…

From September 2025, École Polytechnique and ENS Louis-Lumière will launch “Extended Cinematography” (XCin), a new Master of Science & Technology, to train image specialists capable of designing tomorrow's tools for virtual production in the viedo and film industries. École Polytechnique thus exten…

 The conservation state of parchments is typically assessed using invasive and sometimes destructive investigation techniques. Scientists from Université Paris-Saclay, the CNRS, École Polytechnique, and the French Ministry of Culture[1] have developed a non-destructive and non-invasive advanced opt…

Mainly used in numerous industrial sectors such as transport, space, biomedical and defence, additive manufacturing is constantly developing. In order to provide solutions to the problems of developing additive manufacturing within the various industries, twelve CNRS research laboratories and a dep…

An international collaboration involving the Irradiated Solids Laboratory has just published a paper in Physical Review Letters detailing the mechanisms at work for detecting circularly polarised light using spin-optoelectronic devices called spin photodiodes.

In an article published in the journal Science, an international collaboration involving researchers from the Centre for Theoretical Physics (CPHT*) proposes a tool for estimating the difficulty of many problems yet to be solved, as well as the effectiveness of methods developed to tackle them, inc…
