Explaining 30-year-old ‘hidden order’ physics mystery

12 febrero 2015

A new explanation for a type of order, or symmetry, in an exotic material made with uranium is a major step toward explaining a puzzle that physicists worldwide have been struggling with for 30 years. This ‘hidden order’ appears as a subtle change in the material’s electrical and magnetic properties when the material is cooled to 17.5 degrees above absolute zero or lower — a bone-chilling minus 428 degrees Fahrenheit.
