A scanning tunneling microscope topography scan across a half 4H-SiC unit cell step edge shows two indenene domains (insets) that are mutually rotated by 180°. Selected for 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.

X-ray experiments reveal that a semimetal exhibits “orbital texture”—an exotic electronic structure resulting in spin-dependent electron transport.

Machine learning can be employed to to optimize extraction of information from trajectory data in deterministic chaos.

The quantum-geometric origin of out-of-plane stacking ferroelectric polarization is elucidated and shown to be compatible with the modern theory of polarization.

Adding neutrinos to an existing nucleosynthesis recipe can account for the puzzling existence of neutron-deficient heavy nuclei.

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.
