Abstract
Uranium ditelluride (UTe2) hosts an unusual form of low-temperature superconductivity that has several outstanding experimental signatures pointing to spin-triplet pairing, multiple order parameters, time-reversal symmetry breaking, and in-gap chiral surface states. As if that were not enough, reentrant superconductivity is stabilized at fields greater than 40T, persisting to higher than 65T. After reviewing the unusual main properties of UTe2, I will focus on recent neutron scattering results and what they tell us about electron hybridization, magnetic interactions, and ramifications for superconductivity.
