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.

Non-Fermi liquid behaviour in a correlated flat-band pyrochlore lattice
Nature Physics, Published online: 26 January 2024; doi:10.1038/s41567-023-02362-3
Observations of strong electron correlation effects have been mostly confined to compounds containing f orbital electrons. Now, the study of the 3d pyrochlore metal CuV2S4 reveals that similar effects can be induced by flat-band engineering.

Self-organized intracellular twisters
Nature Physics, Published online: 25 January 2024; doi:10.1038/s41567-023-02372-1
Cytoplasmic flows in the fruit fly oocyte can reorganize cellular components. These structured vortical flows arise through self-organizing dynamics of microtubules, molecular motors and cytoplasm.

Hopping frustration-induced flat band and strange metallicity in a kagome metal
Nature Physics, Published online: 25 January 2024; doi:10.1038/s41567-023-02360-5
Electrons in f orbitals can create localized states that interact strongly and drive strange metal and critical behaviour via the Kondo mechanism. Now a mechanism of geometric frustration enables similar phenomena with d electrons.

Defects show self-constraint in active nematics
Nature Physics, Published online: 24 January 2024; doi:10.1038/s41567-023-02352-5
Studies of a biological active nematic fluid reveal a spontaneous self-constraint that arises between self-motile topological defects and mesoscale coherent flow structures. The defects follow specific contours of the flow field, on which vorticity and strain rate balance, and hence, contrary to expectation, they break mirror symmetry.

Robust continuous time crystal in an electron–nuclear spin system
Nature Physics, Published online: 24 January 2024; doi:10.1038/s41567-023-02351-6
Time crystals spontaneously produce periodic oscillations that are robust to perturbations. A time crystal phase with a long coherence time has now been produced using the electron and nuclear spins of a semiconductor sample.

Origin of the critical state in sheared granular materials
Nature Physics, Published online: 24 January 2024; doi:10.1038/s41567-023-02353-4
When applying sufficient strain, the flow of dense granular matter becomes critical. It is now shown that this state corresponds to random loose packing for spheres with different friction coefficients and that these packings can be mapped onto the frictionless hard-sphere system.

Minimally rigid clusters in dense suspension flow
Nature Physics, Published online: 24 January 2024; doi:10.1038/s41567-023-02354-3
Dense suspensions are granular materials suspended in a liquid at high packing fractions, exhibiting high viscosity. The latter is now shown to be related to the formation of a network of rigid clusters at large shear stress.

Nodal <i>s</i><sub>±</sub> pairing symmetry in an iron-based superconductor with only hole pockets
Nature Physics, Published online: 23 January 2024; doi:10.1038/s41567-023-02348-1
High-precision photoemission measurements determine that the superconducting pairing symmetry in KFe2As2 is the same as in other types of iron-based superconductors, despite having different features in the band structure.

Terahertz-field-driven magnon upconversion in an antiferromagnet
Nature Physics, Published online: 23 January 2024; doi:10.1038/s41567-023-02350-7
Inducing coherent interactions between distinct magnon modes—collective excitations of magnetic order—has been challenging. A canted antiferromagnet has demonstrated coherent magnon upconversion induced by terahertz laser pulses.

Observation of possible excitonic charge density waves and metal–insulator transitions in atomically thin semimetals
Nature Physics, Published online: 23 January 2024; doi:10.1038/s41567-023-02349-0
The mechanism of charge density wave formation has been hard to explain due to accompanying structural distortions. Now low-dimensional HfTe2 is revealed to host a purely electronic exitonic charge density wave driven by reduced screening effects.

A kicked quasicrystal
Nature Physics, Published online: 19 January 2024; doi:10.1038/s41567-023-02357-0
Quasicrystals are ordered but not periodic, which makes them fascinating objects at the interface between order and disorder. Experiments with ultracold atoms zoom in on this interface by driving a quasicrystal and exploring its fractal properties.

Quasi-crystalline order in vibrating granular matter
Nature Physics, Published online: 19 January 2024; doi:10.1038/s41567-023-02364-1
In quasi-crystals, constituents do not form spatially periodic patterns, but their structures still give rise to sharp diffraction patterns. Now, quasi-crystalline patterns are found in a system of spherical macroscopic grains vibrating on a substrate.
