Physicists observe the optical Magnus effect in quantum light for the first time

Hosted the ion-trap experiment

A laser aimed at the center of a trapped atom should interact most strongly at its bright center. It doesn't. Researchers at the Paul Scherrer Institute (PSI) in Switzerland measured the strongest interaction slightly off to one side — a shift they've named the optical Magnus effect, after the physics that curves a spinning table tennis ball.
