  • LENS/CMP Seminar: Sheng Ran on Spin-triplet superconducting state in the nearly ferromagnetic compound UTe2

LENS/CMP Seminar: Sheng Ran on Spin-triplet superconducting state in the nearly ferromagnetic compound UTe2

Tuesday, November 8, 2022

3:00 P.M. – 4:00 P.M.

Location: Swain West 214

Abstract: 

Our recent discovery of the novel spin-triplet superconductivity in UTe2 has inspired a lot of interests in the community [1-3]. Superconducting state of UTe2 closely resembles that of ferromagnetic superconductors, but the normal state is paramagnetic and shows no indication of magnetic ordering. UTe2 exhibits an extremely large, anisotropic upper critical field Hc2, and temperature independent NMR Knight shift in the superconducting state. All these results strongly indicate that the superconductivity in UTe2 is carried by spin-triplet pairs. Even more striking, superconductivity reenters in the magnetic field of 45 tesla and persists up to 65 tesla, which is the upper limit of magnetic field in our current study. These extreme properties reflect a new kind of exotic superconductivity rooted in magnetic fluctuations and low dimensionality. Application of pressure reveals a two-fold enhancement of this unusual superconductivity, and emergence of magnetic order. In this talk, I will review our recent results on UTe2.
