Scientists around the world are busy looking for chiral superconductors, which are predicted to be ideal for building quantum computers. Until now, it has not been easy to determine whether a material is clearly a chiral superconductor or not. Together with their colleagues in Stockholm, theoretical physicists at Utrecht University have recently discovered that a unique effect occurs in chiral superconductors that should be easy to measure. In addition to being interesting from a theoretical perspective, this effect also simplifies the search for a chiral superconductor. The results of the research are published in Physical Review Letters.
