When cold atoms meet nano: A wired quantum node

Physicists at the Kastler Brossel Laboratory in Paris have reached a milestone in the combination of cold atoms and nanophotonics. Using fiber-addressable atoms, they have created the first wired atomic entangled state that ...

How to build a 3-D-printed particle trap with free CERN schematics

CERN is synonymous with accelerators, designed to boost particles to close to the speed of light. But what if you want to slow down a particle and hold it in place while you study it? Particle traps are devices that use electromagnetic ...

Reactive optical matter: Light-induced motion

Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...
