Disordered defect networks evolving from spiral (left) and target (middle) to traveling waves (right) with nonreciprocal interactions in active matter systems.

Today we announce a new initiative, called End Matter, to allow up to about two pages at the end of a Letter of appendixes or other content that specialists will want or need to read.

High-mobility electrons confined to a thin potential well (in a gallium arsenide semiconductor) are used to identify Majorana edge modes, evidence for possible Majorana quasiparticles.

A new device converts a stream of microwave photons into an electric current with high efficiency, which will benefit quantum information technologies.

Focus story on:
O. Stanisavljević et al.
Phys. Rev. Lett. 133, 076302 (2024)

An analysis of the brightest gamma-ray burst ever observed reveals no difference in the propagation speed of different frequencies of light—placing some of the tightest constraints on certain violations of general relativity.

Synopsis on:
Zhen Cao et al. (The LHAASO Collaboration)
Phys. Rev. Lett. 133, 071501 (2024)

A magnet-and-coil system reveals how acoustic waves reflect and refract when the host medium suddenly changes elasticity.

Feature on:
Brian L. Kim, Christopher Chong, and Chiara Daraio
Phys. Rev. Lett. 133, 077201 (2024)

A search for the magnetic monopoles that carry 2 to 45 Dirac units of magnetic charge that could have been produced by heavy-ion collisions places world-leading limits on the monopole masses.

The measurements of the two- and three-particle energy correlators at LHC results in the most precise value of the strong coupling constant ${\alpha }_s(m_Z)$ obtained using jet-substructure observables.

Electrically patterning the walls of a nanochannel could provide a route to creating “valves” that abruptly alter the speed at which a charged fluid flows through a nanofluidic device.

Phys. Rev. Lett. 133, 078201 (2024)

A new mathematical measure of knottiness could help improve the transport efficiencies of subway and road systems, as well as other physical networks.

In non-Hermitian systems, boundary effects are more pronounced than in Hermitian systems.

Many-body quantum interference can be used in molecular transistors and quantum dot nanostructures to engineer fractionalized Kondo anyons.

Instead of training the neural networks with predictions derived from DFT, unsupervised learning by treating the energy functional of variational DFT as the loss function of the neural network yields predictions of material properties.

The policy requires authors to explain where research data can be found starting Sept. 4.

Next in the PRL series of forward-looking Essays, Jun Ye and Peter Zoller envision exciting research paths at the intersection of AMO physics, quantum technologies, and fundamental physics.

APS has selected 156 Outstanding Referees for 2024 who have demonstrated exceptional work in the assessment of manuscripts published in the Physical Review journals. A full list of the Outstanding Referees is available online.
