- Thermopower reveals localized electrons
- Observation of Floquet–Bloch states in monolayer grapheneNature Physics, Published online: 01 May 2025; doi:10.1038/s41567-025-02888-8 Monolayer graphene has been long proposed as a candidate system for Floquet engineering. Time- and angle-resolved photoemission spectroscopy measurements now show the formation of Floquet–Bloch states in this material.
- Anacondas get vertical on the groundNature Physics, Published online: 30 April 2025; doi:10.1038/s41567-025-02875-z Snake locomotion comes in many shapes. A mathematical model explains the non-planar S-start, where parts of the snake’s body lift off the ground.
- Storage-ring laser spectroscopy of accelerator-produced hydrogen-like <sup>208</sup>Bi<sup>82+</sup>Nature Physics, Published online: 28 April 2025; doi:10.1038/s41567-025-02885-x Hyperfine splitting was measured using the laser spectroscopy of accelerator-produced hydrogen-like bismuth ions. This demonstrates the feasibility of such measurements with other exotic ions with low production yields in a storage ring.
- Control of spin currents by magnon interference in a canted antiferromagnetNature Physics, Published online: 23 April 2025; doi:10.1038/s41567-025-02819-7 Controlling the propagation of spin currents with opposite polarities in antiferromagnets has remained challenging. Now the frequency of coherently excited spin waves in a haematite-based device is shown to control the sign of the spin current.
- Skyrmion bags of light in plasmonic moiré superlatticesNature Physics, Published online: 22 April 2025; doi:10.1038/s41567-025-02873-1 Skyrmion bags—textures comprising multiple skyrmions contained within a larger skyrmion—have been reported in several condensed matter systems. Now an optical analogue of these structures has been observed in plasmonic moiré superlattices.
- Scalable microwave-to-optical transducers at the single-photon level with spinsNature Physics, Published online: 22 April 2025; doi:10.1038/s41567-025-02884-y Converting photons from one frequency range to another uses nonlinear effects that are often weak. Strong nonlinearities in rare-earth-ion-doped crystals have now been used to perform microwave-to-optical transduction at the single-photon level.
- Interplay of actin nematodynamics and anisotropic tension controls endothelial mechanicsNature Physics, Published online: 18 April 2025; doi:10.1038/s41567-025-02847-3 Blood flow through a vessel deforms vessel walls. Cells lining these walls sense the changes in pressure as blood flows and reorient their actin fibres in the direction of largest tension.
