Scientists believe so called triplet superconductors could open the door to the most energy efficient technologies ever developed. "A triplet superconductor is high on the wish list of many physicists working in the field of solid state physics," said Professor Jacob Linder. Linder is a physicist at the Norwegian University of Science and Technology's (NTNU' Department of Physics, where he works at QuSpin -- a research centre that brings together some of the university's leading researchers. "Ma...
