Swansea University physicists, as leading members of the ALPHA collaboration at CERN, have demonstrated laser cooling of antihydrogen atoms for the first time.
The groundbreaking achievement produces colder antimatter than ever before and enables an entirely new class of experiments, helping scientists learn more about antimatter in future.
In a paper published today in Nature, the collaboration reports that the temperature of antihydrogen atoms trapped inside a magnetic bottle is reduced when the atoms scatter light from an ultraviolet laser beam, slowing the atoms down and reducing the space they occupy in the bottle – both vital aspects of future more detailed studies of the properties of antimatter.
