Researchers have proposed a method for cooling trapped antihydrogen which they believe could provide 'a major experimental advantage' and help to map the mysterious properties of antimatter that have to date remained elusive.
The new method, developed by a group of researchers from the USA and Canada, could potentially cool trapped antihydrogen atoms to temperatures 25 times colder than already achieved, making them much more stable and a lot easier to experiment on.
The suggested method, which has been published today (Jan. 7, 2013), in IOP Publishing's Journal of Physics B: Atomic, Molecular and Optical Physics, involves a laser which is directed at antihydrogen atoms to give them a 'kick', causing them to lose energy and cool down.
