Single-Positron Quantum Cyclotron Opens New Test of Standard Model Symmetry

Physicists at Northwestern University have trapped a single positron in a device they call a one-positron quantum cyclotron, resolving its lowest quantum states and setting the stage for a precision measurement of its magnetic moment that could deliver the most stringent test yet of CPT invariance.
