In a recent episode of ‘Les visages de la recherche’ (The Faces of Research), viewers were introduced to the work of Ludovic Troian-Gautier.

Particle-exchange heat engines operate without moving parts or time-dependent driving, relying solely on static energy-selective transport. Here, we realize a particle-exchange quantum heat engine based on a single diradical molecule, which is only a few nanometers in size. We experimentally investigate its operation at low temperatures and demonstrate that both the power output and efficiency are significantly enhanced by Kondo correlations, reaching up to 53% of the Curzon–Ahlborn limit. These results establish molecular-scale particle-exchange engines as promising candidates for low-temperature applications where extreme miniaturization and energy efficiency are paramount.

Prof. G.-M. Rignanese was selected to develop the GEMPROMISE project—Generative machine learning for combined process control and materials design—with two other Principal Investigators from the Swiss Federal Institute of Technology in Lausanne (EPFL) and the French National Center for Scientific Research (CNRS).

Une équipe internationale de physiciens impliquant l’Université d’Amsterdam, l’Université de Torún (Pologne) et l’UCLouvain, est parvenue à confiner des molécules d’hydrogène au sein d’un faisceau laser. Cette prouesse expérimentale, qui confirme une prédiction théorique vieille de 50 ans, vient d’être publiée dans la revue Physical Review Letters.
