AMHERST, Mass.—Building on his own previous research, Amherst College professor David S. Hall ’91 and a team of international collaborators have experimentally identified a pointlike monopole in a quantum field for the first time. The discovery, announced this week, gives scientists further insight into the elusive monopole magnet, an elementary particle that researchers believe exists but have not yet seen in nature.

AMHERST, Mass.—Nearly 85 years after pioneering theoretical physicist Paul Dirac predicted the possibility of their existence, an international collaboration led by Amherst College Physics Professor David S. Hall ’91 and Aalto University (Finland) Academy Research Fellow Mikko Möttönen has created, identified and photographed synthetic magnetic monopoles in Hall’s laboratory on the Amherst campus.
