Nature Physics offers news and reviews alongside top-quality research papers in a monthly publication, covering the entire spectrum of physics. Physics addresses the properties and interactions of matter and energy, and plays a key role in the development of a broad range of technologies. To reflect this, Nature Physics covers all areas of pure and applied physics research. The journal focuses on core physics disciplines, but is also open to a broad range of topics whose central theme falls within the bounds of physics.

- Nature Physics, Published online: 27 June 2025; doi:10.1038/s41567-025-02938-1 The photoinduced hidden metallic state in 1T-TaS2 has so far been stabilized only at cryogenic temperatures. Now it is shown that accessing an additional mixed-phase long-lived metastable state can stabilize the hidden phase at higher temperatures.
- Nature Physics, Published online: 26 June 2025; doi:10.1038/s41567-025-02936-3 When a charge current, a temperature gradient and a magnetic field are applied orthogonally to each other, a conductor is expected to heat or cool. This so-called transverse Thomson effect has now been observed for a bismuth–antimony alloy.
- Nature Physics, Published online: 26 June 2025; doi:10.1038/s41567-025-02956-z Graphene multilayers can host heavy electrons in flat bands alongside light electrons in Dirac cones. Local probes now reveal that a finite Dirac electron population persists at the Fermi level while correlated states form in the flat bands.
- Nature Physics, Published online: 26 June 2025; doi:10.1038/s41567-025-02935-4 It is unclear how cell compartmentalization emerged in prebiotic conditions. Now it is shown that a temperature gradient in a confined space can bring the core components of a cell together.
- Nature Physics, Published online: 24 June 2025; doi:10.1038/s41567-025-02941-6 As many classical neural networks get larger, they can be described as Gaussian processes, the generalization of the normal distribution to infinite dimensions. A similar connection has now been proven for quantum neural networks.
- Nature Physics, Published online: 20 June 2025; doi:10.1038/s41567-025-02947-0 Tissues are usually modelled as viscoelastic materials. Now it is shown that intercellular fluid flow, rather than viscoelastic behaviour, dominates the immediate mechanical response of tissues.
- Nature Physics, Published online: 19 June 2025; doi:10.1038/s41567-025-02939-0 Time-resolved photoemission shows evidence of Floquet states in graphene, resolving a long-standing debate and unlocking engineering of quantum phases with light in semi-metals.
