Broken time-reversal symmetry in superconducting UPt3

Researchers at the University of Notre Dame, in partnership with those at Northwestern University, are a step closer to understanding how superconductors can be improved for reliability in future quantum computers.

The team, led by by Morten Eskildsen, professor in the Department of Physics at Notre Dame and William Halperin from Northwestern University, achieved a new discovery in the field of topological superconductivity. The materials are at the forefront of research in quantum computing and quantum sensing.

The team demonstrated in their paper, published in March in Nature Physics, that the superconducting compound UPtbreaks time-reversal symmetry, where superconducting electrons spontaneously circulate around a specific axis within the crystalline structure of the material.
