Splitting Atomic Clouds with Laser Tweezers (video) University of Otago Share Print E-Mail Loading video... Caption Physicists from New Zealands' University of Otago 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. Here the researchers use the technology to split a single ultracold cloud of rubidium atoms sequentially into 32 daughter clouds, spreading them out over nearly half a centimetre.
