In a paper which will shortly appear in Physical Review Letters, School of Physics and Astronomy Professor Oriol Valls along with lead author Klaus Halterman (China Lake, Naval Warfare Center) and co-author Paul Barsic (University of Minnesota) show that triplet superconducting pairing, odd in time, is induced in clean heterostructures consisting of an ordinary s-wave superconductor sandwiched between ferromagnets.
