Saïda Guellati-Khelifa and her team achieved a precise determination of the fine-structure constant using atom interferometry. They developed an in situ method to probe the wave-vector dispersion as experienced by atoms within the vacuum chamber, using a Bose–Einstein condensate as a moving probe.

Pauline Yzombard helped achieve the first laser cooling of trapped negative ions, implementing a decades-old theoretical method just months before the project’s funding ended. Her work revived a long-stalled project and opened new possibilities for precision experiments with anions.

Nancy Paul and her team performed the first demonstration of a quantum X-ray sensor (microcalorimeter) with an atom composed of antimatter. These experimental techniques open a new window for studying fundamental theories such as quantum electrodynamics.

Valentina Parigi and her team are working at the interface between network science and quantum optics. The team experimentally demonstrated an optical simulator for open quantum systems with complex network environments. This system provided an ideal testbed for studying quantum non-Markovianity.

Mark your calendars for next Wednesday's #LKBseminar!

We're delighted to host Tanja Mehlstäubler from Physikalisch-Technische Bundesanstalt, PTB & Leibniz Universität Hannover.

📍 11 a.m. on February 18, 2026

Today is the International Day of Women and Girls in Science, which means that it is a perfect moment to highlight some of the most striking scientific results obtained by the women in our lab!

Alice Sinatra and her team laid the theoretical foundations for a precise sensor network.
By splitting a Bose–Einstein condensate into correlated atomic clouds, they succeeded in jointly measuring physical parameters with a precision exceeding the standard quantum limit.

Elisabeth Giacobino is not only the president of the French Physical Society; she also has a rich research career filled with groundbreaking results.
Elisabeth and her team demonstrated that an optical parametric oscillator consisting of a nonlinear crystal pumped by a laser emits twin quantum beams

thanks for this initiative! 🙏

☮️ what a very nice initiative, especially welcomed in those times. Signed! 🙌

wow.. same for me.. at least for my ANR JCJC I thought so... for my CNRS position I knew my section is not really doing "positive discrimination" at all. (Still I heard I got the job more easily because I was a woman. 😐)

Thanks for sharing this 🙏

Have you ever heard that women have more chances than men of getting grants or positions in academia? Of course you have, and here are my personal views on this. With the shocking revelation that no, it is NOT TRUE ! (1/n)

Hello! our program is already full, unfortunately.. ☹️
We are still waiting for confirmations, but there might be some industry interventions also (spoilers 🤐🤞)
So hopefully this will lead to discussions !

Pourquoi y a-t-il si peu de femmes récompensées par le Prix Nobel ? A l'occasion d'une matinale spéciale sur l'avenir vu par les Prix Nobel, Avec sciences interroge la faible proportion de femmes parmi les lauréats. Sous-représentation en sciences, carrières inégales ...

Pourquoi y a-t-il si peu de femmes récompensées du prix Nobel ? Au moins 3 raisons peuvent être invoquées : sous-représentation des femmes en sciences, inégalités de carrières et effet Matilda. Quelles solutions face à cela ?

Analyse « La misogynie se ressent toujours au quotidien » Dénoncer les inégalités femme-homme, c’est salutaire. Proposer des solutions, c’est concret. Deux physiciennes, Maurine Montagnat et Christiane Koch, ont décidé de faire bouger les choses dans leur discipline.
