VMD est incroyable. ça va faire 20 ans que je l'écoute parler et que je la croise de temps en temps, je ne sais pas comment elle fait. Elle a un ton d'une justesse époustouflante pour faire passer ses messages, dialoguer sans transiger.

What result are you the most proud of? (This me 😊) #WomenInSTEM

Lab. Kastler Brossel@lkblab.bsky.social · 6mo ago

One of the experimental results that Hanna Le Jeannic is most proud of dates back to her postdoctoral work at the Niels Bohr Institute in Copenhagen. There, she studied the nonlinear interaction between two photons arriving simultaneously at a two-level quantum emitter.

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 👉 For more details on this seminar : https://www.lkb.fr/evenements/seminaires-du-lkb/

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! @cnrs.fr @college-de-france.fr @normalesup.bsky.social ©picture @sorbonne-universite.fr

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. www.lkb.fr/en/laboratoi...

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

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