- Neutron scattering and thermodynamic evidence for emergent photons and fractionalization in a pyrochlore spin ice
- Feedback between F-actin organization and active stress governs criticality and energy localization in the cell cytoskeletonNature Physics, Published online: 18 June 2025; doi:10.1038/s41567-025-02919-4 Self-organized criticality can occur in cellular systems, but its origins remain unclear. Now it is shown that cytoskeletal criticality is influenced by the F-actin architecture and myosin active stress.
- Driven quantum fluids sound like supersolidsNature Physics, Published online: 18 June 2025; doi:10.1038/s41567-025-02934-5 Quantum gases develop modulated patterns when subjected to a continuous drive. An experiment has now demonstrated that, in a driven quantum system, the sound propagates with two distinct speeds, reflecting both superfluid and crystalline properties — a feature of supersolidity.
- From actin to actionNature Physics, Published online: 18 June 2025; doi:10.1038/s41567-025-02937-2 Cells undergo structural rearrangements to enable migration and changes in morphology. A study using reconstituted actomyosin revealed that these earthquake-like events are driven by F-actin organization and active stress generation.
- Emergent exchange-driven giant magnetoelastic coupling in a correlated itinerant ferromagnetNature Physics, Published online: 17 June 2025; doi:10.1038/s41567-025-02893-x Magnetostructural changes are usually small and driven by spin–orbit coupling. Now, electron–lattice coupling enhanced by exchange interactions is shown to produce giant magnetostriction in a correlated ferromagnet.
- Experimental demonstration of breakeven for a compact fermionic encodingNature Physics, Published online: 16 June 2025; doi:10.1038/s41567-025-02931-8 Digital quantum simulations of fermionic models have so far been based on the Jordan–Wigner encoding, which is computationally expensive. An alternative and more efficient encoding scheme is now demonstrated in a trapped-ion quantum computer.

- Student interactions with generative AINature Physics, Published online: 13 June 2025; doi:10.1038/s41567-025-02932-7 Students are turning to generative AI chatbots like ChatGPT to support their physics learning. Here, I examine one student’s interactions with ChatGPT on an exam recuperation assignment and the student’s reflections on the process.
