The quantum ‘boomerang’ effect has been seen for the first time

Jostled particles return to their starting points in certain materials

New experiment demonstrates quantum boomerang effect

In the quantum boomerang effect, particles return to their starting positions, on average, after a nudge. A new experiment (shown) demonstrates a version of the effect using lithium atoms.

Some quantum particles gotta get right back to where they started from.
