Trajectories of electrons in interaction with colliding high-intensity laser pulses.

Experiments reveal the factors that determine the friction between the single-atom-thick layers in van der Waals materials, which may have uses in lubrication technology.

Vacancy-induced impurity states in twisted bilayer graphene provide a tunable system to probe the critical destruction of the Kondo effect.

Breaking of inversion symmetry in the charge and orbital ordered phase of TiSe$2_{}$ has been unambiguously shown using x-ray diffraction.

Superconducting gaps on the Fermi surface of infinite-layer nickelates show a phonon-mediated pairing mechanism, suggesting that these superconductors are not conventional after all.

A fully relativistic treatment of the statistics of galaxy distributions may explain the parity violation recently seen in the galaxy trispectrum.

The spin-dependent hybrid skin-topological effect is experimentally realized on a non-Hermitian phononic crystal, which might lead to new methods for non-Hermitian wave manipulations.

Gravitational-wave signals from black hole mergers could reveal the presence of "gravitational atoms"—black holes surrounded by clouds of axions or other light bosons.

A qubit chain described by the cluster Hamiltonian can host a nondegenerate gapped topological phase protected by a noninvertible symmetry.

Ultraviolet photons induce potassium niobate to behave like a potent solid-state refrigerant, according to new calculations.

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

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.

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.
