Spin-triplet topological superconductors should exhibit many unprecedented electronic properties, including fractionalized electronic states relevant to quantum information processing. Although UTe2may embody such bulk topological superconductivity1–11, its superconductive order parameter Δ(k) remains unknown12. Many diverse forms for Δ(k) are physically possible12in such heavy fermion materials13. Moreover, intertwined14,15density waves of spin (SDW), charge (CDW) and pair (PDW) may interpose, with the latter exhibiting spatially modulating14,15superconductive order parameter Δ(r), electron-pair density16–19and pairing energy gap17,20–23. Hence, the newly discovered CDW state24in UTe2motivates the prospect that a PDW state may exist in this material24,25. To search for it, we visualize the pairing energy gap with μeV-scale energy resolution using superconductive scanning tunnelling microscopy (STM) tips26–31. We detect three PDWs, each with peak-to-peak gap modulations of around 10 μeV and at incommensurate wavevectorsPi=1,2,3that are indistinguishable from the wavevectorsQi=1,2,3of the prevenient24CDW. Concurrent visualization of the UTe2superconductive PDWs and the non-superconductive CDWs shows that everyPi:Qipair exhibits a relative spatial phaseδϕ≈ π. From these observations, and given UTe2as a spin-triplet superconductor12, this PDW state should be a spin-triplet PDW24,25. Although such states do exist32in superfluid3He, for superconductors, they are unprecedented.
