Sodium nanoparticles of 5,000 to 10,000 atoms diffract through ultraviolet laser gratings, reaching macroscopicity μ = 15.5 in a Nature paper from the Arndt group.
A Tokyo University of Science team has observed first-order matter-wave diffraction of positronium passing through a few-layer graphene grating, the first direct evidence that the short-lived electron-positron atom behaves as one coherent quantum object and a step toward gravity tests on antimatter.
Researchers at CSIRO, the University of Melbourne, and RMIT have built and tested a quantum battery prototype that completed a full charge-store-discharge cycle for the first time, demonstrating a counterintuitive property where charging speed increases with battery size.
