After 25 years of development, the ACES/PHARAO space mission will launch to the International Space Station on April 21, 2025, at 10:15 a.m. Paris time, from Cape Canaveral, Florida.
Superfluid Helium and Negative Pressures
Recent results published in Physical Review Letters challenge previous estimates of the cavitation pressure.
Dark-soliton molecules in a polariton superfluid
Experiments performed the Quantum Optics team show that dark solitons in a quantum fluid of polariton quasiparticles can bind together to form a soliton molecule

A tiny mirror – Physicists reflect light with only 2000 atoms
In the September 23th issue of the Physical Review Letters, Prof. Julien Laurat and his team report they have managed to realize an efficient mirror constituted of only 2000 atoms.
After the proton, now the deuteron
Again, the deuteron radius is smaller than expected anfd in good agreement with the proton radius deduced from muonic hydrogen spectroscopy, thus reinforcing the “proton radius puzzle”.
Schrödinger’s cats to measure the electric field of a single electron
Des physiciens viennent de réaliser un électromètre ultrasensible qui repose sur l’utilisation d’atomes excités portés dans une superposition d’états de type “chat de Schrödinger.”
Controlled Generation of Vortices in a Superfluid of Light
“One of its most intriguing properties is superfluidity, which manifests as the absence of friction when the fluid flows.”
The Microscope Satellite and the Equivalence Principle
The CNES Microscope satellite was launched on Monday, April 25. Its goal is to test the equivalence principle.
A new ultra-fast, energy-efficient optical coprocessor for big data
Sylvain Gigan, a member of LKB, is one of the six inventors behind the LightOn project.
Gravitational Waves: And Two!
Three months after the announcement of the first detection, scientists from the LIGO and Virgo collaborations present a second observation of the coalescence of two black holes, revealed by the gravitational waves emitted during this event. Although the signal is weaker than the first, this second detection is also confirmed with more than 99.99999% confidence.
