🧲 Competing magnetic interactions in the pyrochlore lattice can freeze into a new “mixed” magnetic order — or into a spin nematic phase with none at all, just broken rotational symmetry. Read the study: go.aps.org/4xvbG0l

🧠 This carbon nanotube foam remembers exactly how it was squeezed — like a hard drive, but mechanical. A new paper shows the first clean case of return point memory in a soft, elastic material, driven by nanoscale friction between nanotubes: go.aps.org/4h8P0Nq

A new study shows that active cavity feedback cuts polariton decay rates by more than 10x, boosting cooperativity and enabling strong photon-magnon-phonon coupling. These results overcome a major material limit for hybrid quantum systems. Read more: go.aps.org/3TsHhlu
