Tweezers constructed from laser beams can maintain and transfer a single atom

The way in which gravity impacts the quantum realm has up to now remained mysterious. However an experiment that makes use of lasers as a pair of tweezers might let researchers assess how Earth’s gravitational pull impacts an atom that ticks like a clock.
At extraordinarily chilly temperatures – assume billionths of a level above absolute zero – quantum results make atoms behave like “matter waves” slightly than particles. Physicists have lengthy taken benefit of this: by colliding completely different matter waves and measuring the ensuing ripples, they’ll determine the forces…
