Experiments promote a curious flipside of decaying monopoles: a reality where particle physics is quite literally turned on its head. The field of quantum physics is rife with paths leading to tantalizing new areas of study, but one rabbit hole offers a unique vantage point into a world where par

Monopoles remain an elusive concept in the arena of quantum physics. As the name suggests, monopoles are the solitary counterpart of dipoles, which carry a positive charge at their north pole and a negative charge at the south. In contrast, a monopole carries only either a positive or negative charge.

“Think of the monopole as an egg teetering at the top of a hill,” Möttönen said. “The slightest perturbations can send it crashing down. In the same way, monopoles are subject to noise that triggers their decay into Alice rings.” “From a distance, the Alice ring just looks like a monopole, but the world takes a different shape when peering through the center of the ring,” Hall said.
