Nature Physics
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.

Breaking fast and slow
Nature Physics, Published online: 05 February 2024; doi:10.1038/s41567-024-02389-0
When cracks creep forward in our three-dimensional world, they do so because of accompanying cracks racing perpendicular to the main direction of motion with almost sonic speed. Clever experiments have now directly demonstrated this phenomenon.

Dipolar spin wave packet transport in a van der Waals antiferromagnet
Nature Physics, Published online: 01 February 2024; doi:10.1038/s41567-024-02387-2
Understanding the mechanism by which magnons—the quanta of spin waves—propagate is important for developing practical devices. Now it is shown that long-range dipole–dipole interactions mediate the propagation in a van der Waals antiferromagnet.

A quantum collaboration for flat bands
Nature Physics, Published online: 31 January 2024; doi:10.1038/s41567-024-02397-0
Multiple mechanisms can create electrons with reduced kinetic energy in solids. Combining these mechanisms now appears as a promising route to enhancing quantum effects in flat band materials.

Terahertz field-induced nonlinear coupling of two magnon modes in an antiferromagnet
Nature Physics, Published online: 31 January 2024; doi:10.1038/s41567-024-02386-3
Magnons—quanta of spin waves—have potential applications in signal processing technology. But it is challenging to obtain coupling between different magnons. Now a study achieves this by demonstrating nonlinear magnon mixing in an antiferromagnet.

Correlated order at the tipping point in the kagome metal CsV<sub>3</sub>Sb<sub>5</sub>
Nature Physics, Published online: 31 January 2024; doi:10.1038/s41567-023-02374-z
The electronic transport properties of charge-ordered kagome metals are controversial. Now careful measurements on unperturbed samples show that previously measured anisotropy in the transport occurs only when external perturbations are present.

Phonons bend to magnetic fields
Nature Physics, Published online: 30 January 2024; doi:10.1038/s41567-023-02288-w
Phonons do not carry spin or charge, but they can couple to an external magnetic field and cause a sizable transverse thermal gradient. Experiments suggest that phonon handedness is a widespread effect in magnetic insulators with impurities.

Phonon chirality from impurity scattering in the antiferromagnetic phase of Sr<sub>2</sub>IrO<sub>4</sub>
Nature Physics, Published online: 30 January 2024; doi:10.1038/s41567-024-02384-5
The thermal Hall effect of phonons does not yet have a definitive explanation. Now a careful study of doped Sr2IrO4 suggests that the mechanism involves the scattering of phonons by impurities embedded in an antiferromagnetic environment.

The interplay of field-tunable strongly correlated states in a multi-orbital moiré system
Nature Physics, Published online: 30 January 2024; doi:10.1038/s41567-024-02385-4
Heterostructures of transition metal dichalcogenides are known to simulate the triangular-lattice Hubbard model. Now, by combining a monolayer and bilayer of different materials, this idea is extended to multi-orbital Hubbard models.

Propagation of extended fractures by local nucleation and rapid transverse expansion of crack-front distortion
Nature Physics, Published online: 29 January 2024; doi:10.1038/s41567-023-02365-0
Understanding the three-dimensional nature of fracture formation and dynamics is challenging. Experiments now show that a fracture front, after originating at a particular locus in a material, propagates jump-wise and expands transversely at high speed.
