Unconventional superconductivity

Elastic response reveals the pairing symmetry

The determination of the order parameter symmetry is a critical issue in the study of unconventional superconductors. Ultrasound measurements on UTe2, a candidate spin-triplet superconductor, now provide evidence for the single-component nature of its order parameter.
