The researchers devised a single-positron quantum cyclotron to probe the particle’s properties. Credit: Gerald Gabrielse/Northwestern University Physicists have now suspended a single positron (the antimatter equivalent of an electron) in air and cooled it to its lowest possible energy state. The facility will allow researchers to study the magnetic properties of the positron with unprecedented … Read more
