The electric-field structure in plasma wakefield accelerators has been detected experimentally with femtosecond resolution for the first time.

A proposal for a new mechanism of dark matter production suggests that the abundance of dark matter may be set by its inelastic scattering rate, instead of its annihilation rate.

Electron spin resonance experiments demonstrate that graphene possesses an intrinsic spin-orbit coupling.

A dramatic scenario in which a compact black hole eats a spinning neutron star from inside might explain a nearby galaxy’s unexpectedly high abundance of heavy elements.

The conductance of a molecule standing perpendicular to a substrate is found to be dependent on the geometry, orbital symmetries, and bonds of the molecule.

The ATLAS collaboration has placed an upper limit on the decay rate of Higgs bosons into pairs of muons within a factor of three of the Standard Model prediction.

Previously predicted oscillations in the electronic states of atoms after the dissociation of a hydrogen molecule are observed experimentally.

Experiments show that the mass of an object determines whether it slides down a sandy slope, which may explain why insect predators called antlions can trap ants in sand pits.

Snapshot of spiral waves resulting from the spatiotemporal dynamics of excitable media. White circles indicate the phase singularities or organizing centers of the waves.

The first experimental study of frictional drag effect between two monolayer sheets of graphene separated by a boron nitride spacer shows on strong magneto- and Hall-drag signals that depend on the Landau level filling of each graphene layer.

In 2014, two groups separately realized a single-photon transistor using an ensemble of cold atoms. This goal, sought for decades, was achieved using Rydberg excitations to mediate interactions between individual photons. These papers additionally realize a system of strongly interacting particles that may have implications for many-body physics problems.
