An atomic conveyor belt/catapult that uses lasers to position individual atoms has been developed, researchers report in the June 15 issue of Science.
The German researchers use laser beams to retard fast-moving caesium atoms, which they hold in a trap of light and magnetic fields. The team then pulls these “cold” atoms out of the trap one at a time using two laser beams. They can stop… read more
