Dynamic phase transition in 1T-TaS<sub>2</sub> via a thermal quench
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.

Atoms revolt against tweezer-imposed order
Nature Physics, Published online: 27 June 2025; doi:10.1038/s41567-025-02946-1
The combination of optical tweezer arrays with high-finesse cavities opens the door to the study of mesoscopic finite-size effects in the critical dynamics and optomechanical response of atomic ensembles.

Tunable interplay between light and heavy electrons in twisted trilayer graphene
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.

Membraneless protocell confined by a heat flow
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.

Observation of the transverse Thomson effect
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.

Quantum neural networks can be normal
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.

Intercellular flow dominates the poroelasticity of multicellular tissues
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.

Floquet states in graphene revealed at last
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.
