Control of spin currents by magnon interference in a canted antiferromagnet
Nature 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.

Scalable microwave-to-optical transducers at the single-photon level with spins
Nature 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.

Skyrmion bags of light in plasmonic moiré superlattices
Nature 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.

Interplay of actin nematodynamics and anisotropic tension controls endothelial mechanics
Nature 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.

We need to talk about heliophysics
Nature Physics, Published online: 18 April 2025; doi:10.1038/s41567-025-02851-7
Heliophysics focuses on understanding the different processes in the solar system and the influence of the Sun on space and planets. Collaboration between subfields of heliophysics and different communities needs to improve to advance the field.

Impact of impurities on crystal growth
Nature Physics, Published online: 15 April 2025; doi:10.1038/s41567-025-02870-4
Crystallization processes are influenced by the presence of impurities. Colloid experiments now reveal two distinct types of growth mode that depend on the extent to which a crystallizing system can remove impurity particles from its growth front.

Hamiltonian engineering of collective XYZ spin models in an optical cavity
Nature Physics, Published online: 15 April 2025; doi:10.1038/s41567-025-02866-0
Spin models that can be emulated by quantum simulators are usually restricted to systems with conserved total magnetization. The tuning of photon-mediated interactions between atoms in a cavity enables the implementation of more general models also useful for quantum sensing tasks.

Ultrafast room-temperature valley manipulation in silicon and diamond
Nature Physics, Published online: 14 April 2025; doi:10.1038/s41567-025-02862-4
Control over electron populations in different conduction band minima in semiconductors can be used to store and process information. Now the ultrafast optical manipulation of such electrons at room temperature has been demonstrated in silicon and diamond.
