Physicists have uncovered how direct atom-atom interactions can amplify superradiance, the collective burst of light from atoms working in sync. By incorporating quantum entanglement into their models ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

WEST LAFAYETTE, Ind. — Matter gets weird at the quantum scale, and among the oddities is the Efimov effect, a state in which the attractive forces between three or more atoms bind them together, even ...

Repeatedly energising a collection of ultracold atoms should destroy their collective structure, but quantum effects seem to counteract the process. “We expected to see the opposite,” says Nӓgerl. The ...
