Rare quantum behavior found in plutonium could improve future nuclear technology

SMRTR summary

Scientists at Idaho National Laboratory discovered a rare quantum property in plutonium hexaboride, a compound studied for over 80 years without revealing this behavior. This "topological Kondo insulating state" allows materials to both conduct and block electricity, potentially improving nuclear reactor safety, extending nuclear material lifespans, and advancing quantum computing and sensing technologies.
