A laser excites a low energy isomeric state in a nucleus of thorium-229 embedded in a crystal of calcium fluoride. Selected for a Viewpoint in Physics and an Editors’ Suggestion.

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.

Researchers predict that several exotic states of matter can exist in semiconductor structures hosting electrons in one layer and holes in another.

A universal, one-parameter scaling theory is developed that describes transport behavior from the ballistic to the diffusive regime in multimode nonlinear photonic circuits.

Tensor network methods and reinforcement learning are combined to solve dynamical optimization tasks relevant to both nonequilibrium physics and machine learning.

If classical systems were to coexist with “anticlassical” systems (coined here) then an observer with access to both systems could measure Bell nonlocality and other nonclassical features.

A universal and fully experimental algorithm allows for extraction of orbital angular momentum from 2D quantum materials.

Bounds on fluctuations for nonequilibrium conditions provide performance limitations of heat engines at the nanoscale.

The Drude peak displacements in the optical conductivity of strange metals are a consequence of a strong electron-phonon interaction.

A reexamination of the X(2370) state using high-precision $J/\psi$ decay data uncovers its quantum number as $0^{-+}$, which is consistent with it being a pseudoscalar glueball candidate.

Dual-rail erasure qubits are characterized in a superconducting cavity architecture that allows for an improved error correction.

To describe the electron beam attenuation lengths in solids, in addition to a single-exponential law, momentum relaxation must also be taken into account.

A method for freely adjusting the parameters of a loop of optical fiber enables the exploration of exotic topological phases of matter.
