The authors discover a “Yin-Yang” vortex on the (011) surface of UTe2 under a perpendicular magnetic field by scanning tunneling microscopy/spectroscopy. Via theoretical modeling, they conclude that the observation of this vortex confirms the spin-triplet pairing of UTe2 and imposes constraints on the d-vector.
