Laser cooling of antihydrogen atoms
The photon—the quantum excitation of the electromagnetic field—is massless but carries momentum. A photon can therefore exert a force on an object upon collision1. Slowing the translational motion of atoms and ions by application of such a force known as laser cooling, was first demonstrated 40 year...
