I am quite happy to share our latest work from the #Rydberg Atoms team of @lkblab.bsky.social, that just appeared on arXiv, by Yohann Machu and all the Rb team @college-de-france.fr @psl-univ.bsky.social @normalesup.bsky.social @cnrs.fr @sorbonne-universite.fr (1/14)

arxiv.org/abs/2509.24691
Four ensembles of atoms arranged on a square. Within every ensemble, there are three atoms. On the two left ensembles, the central atom is depicted with a yellow torus (circular Rydberg level) and the two outer ones with a red sphere (ground state). In the two left ensembles, the central atom is depicted by a small blue torus (circular level), the left atom as a large green sphere (other Rydberg level) and the right atom as a red sphere. All red-sphere atoms are illuminated by a red beam that represents a laser trap.

Congratulations to physicist Christophe Salomon who has just won a 2025 #BalzanPrize!

This award is related to his work on atoms and ultra-precise measurement of time.

He will receive c.€800K, half of which must then be invested in research.
