Three-channel Kondo effect discovered in cubic holmium compound

A scientist from Tokyo Metropolitan University has applied numerical methods to capture the hallmarks of a quantum phenomenon known as the three-channel Kondo effect in an f-electron system for the first time. Professor Takashi Hotta showed how electrons around a holmium +3 ion interact with conduction electrons and give rise to a predicted residual entropy value at ultra-low temperatures. The work also predicts the kind of real materials which might show this effect.
