Physicists split and collide ultracold atom clouds using steerable ‘optical tweezers’

Physicists have pushed the frontiers of quantum technology by developing a steerable ‘optical tweezers’ unit that uses intense laser beams to precisely split minute clouds of ultracold atoms and to smash them together. The researchers’ feat is set to enhance efforts to understand the mysterious ways that atoms interact at temperatures of less than a millionth of a degree above absolute zero.
