Chiral liquid numerical simulation showing the particle displacements (arrows) and local bond orientations (color).

Landau theory adapted to the zero spin-orbit coupling limit captures features of altermagnets, a class of colinear magnets with spin-split bands.

Using thin layers of chiral nematic liquid crystals, researchers have observed the formation dynamics of skyrmions.

The radio frequency response of the Wigner crystal at low filling factors reveals the details of the pinning mode resonance and shows how this mode is affected by disorder, and which disorder is driving the frequency dependence.

3D tracking simulations show the effectiveness of a space-charge mitigation method that uses pulsed linear electron lenses to effectively increase the space charge limit in hadron synchrotrons by 50%.

Precision measurement of the fine structure in helium makes it possible to perform an independent measurement of the fine structure constant.

The first experimental measurement of the incoherent photonuclear production of $J/\psi$ in ultraperipheral heavy-ion collisions is better explained by the presence of subnuclear quantum fluctuations of the gluon field.

Dense ensembles of laser-cooled molecules allow the observation of molecular collisions—a result that could lead to applications of cold molecular gases in quantum simulation and fundamental physics tests.

Muon spin rotation measurements of the magnetic ground state of a high-purity single-crystal RuO${}_2$, in combination with DFT calculations, show there is no bulk antiferromagnetic order as previously reported.

The verification of a 63-year-old hypothesis indicates that nonequilibrium statistical mechanics could act as a theoretical framework for describing turbulence.

Strain localization in shear bands is key to the yielding and material failure of amorphous systems subject to oscillatory shear.

Millijoule THz emission has been experimentally observed in the backward direction of laser wakefields generated by focusing an intense femtosecond laser pulse on a gas nozzle.
