A magnetic field boost for superconductors

Article metrics

High-magnetic-field experiments on the recently discovered unconventional superconductor UTe2 are consistent with p-wave pairing arising while time-reversal symmetry is broken. In turn, this suggests that this material is a candidate for a chiral superconductor that may be exploited for topological quantum computing.
