Hund’s exchange interaction energy in two-dimensional materials is challenging to extract from experiments. Now, this is achieved in rhombohedral graphene, which allows an estimate of the interactions that drive the variety of correlated states in this material.

- Isospin magnetic texture and intervalley exchange interaction in rhombohedral tetralayer graphene
- Impact of low-energy spin fluctuations on the strange metal in a cuprate superconductorNature Physics, Published online: 30 September 2025; doi:10.1038/s41567-025-03034-0 The underlying physics of the strange metal phase observed in many strongly correlated materials is not well understood. Now, evidence emerges that antiferromagnetic spin fluctuations play an important role.
- From bending to lightningNature Physics, Published online: 30 September 2025; doi:10.1038/s41567-025-03050-0 Laboratory measurements reveal that ice exhibits flexoelectricity — the generation of an electrical field upon bending. This flexoelectricity may be the microscopic mechanism for the mysterious charge separation that creates lightning in thunderstorms.
- Gate-tunable double-dome superconductivity in twisted trilayer grapheneNature Physics, Published online: 30 September 2025; doi:10.1038/s41567-025-03040-2 Two regions of superconductivity are observed in the phase diagram of magic-angle twisted trilayer graphene. This may yield insight into the superconducting mechanism in moiré materials.
- Cool nanoparticlesNature Physics, Published online: 30 September 2025; doi:10.1038/s41567-025-03051-z High-purity quantum states, essential for quantum technological applications, were achieved by cooling optically levitated silica nanoparticles.
- Simple cell motility on adhesive gradientsNature Physics, Published online: 26 September 2025; doi:10.1038/s41567-025-03010-8 Haptotaxis — a mechanism of sensing adhesive gradients by motile cells — was thought to rely on complex mechanochemistry. It turns out that this mechanism is simply based on the difference of adhesive friction at cell front and rear.
- Sub-picosecond topological phase transition in nonlinear exciton–polariton superlatticesNature Physics, Published online: 26 September 2025; doi:10.1038/s41567-025-03031-3 Achieving versatile, tunable, real-time topological photonic system is challenging. Now this is accomplished by designing superlattices of WS2 and a polymer embedded in a microcavity.
- Single-cell migration along and against confined haptotactic gradientsNature Physics, Published online: 26 September 2025; doi:10.1038/s41567-025-03015-3 Haptotaxis was traditionally seen as migration up protein gradients. It is now shown that cells can also oscillate or migrate down the gradient.
