Topological nodal <i>i</i>-wave superconductivity in PtBi<sub>2</sub>
Nature, Published online: 19 November 2025; doi:10.1038/s41586-025-09712-6Angle-resolved photoemission spectroscopy shows that Weyl semimetal PtBi2 harbours nodes in its superconducting gap, implying unconventional i-wave pairing symmetry.
