The final results of the MICROSCOPE mission reach record precision The MICROSCOPE mission has just confirmed the principle of equivalence with a record precision of a few 10-15. It thus proves that bodies fall in vacuum with the same acceleration regardless...
SUPERFLUID HELIUM AND NEGATIVE PRESSURES Low temperature liquid helium-4 is a model material for condensed matter physics for two reasons. First, atomic interactions are weak and quantum effects play an important role on the macroscopic scale. Secondly,...
Fundamental constants: the molecular hydrogen ion joins the play The HD+ molecule, composed of a proton, a deuteron and an electron, is along with its isotopes such as H2+ or D2+, the simplest molecule. As such, it is a valuable tool to test our understanding of...
Connecting the quantum internet Researchers at the Kastler Brossel Laboratory in Paris have succeeded in implementing a novel “hybrid” entanglement swapping protocol, bringing within reach the connection of disparate platforms in a future, heterogeneously-structured,...
