Magnetic interaction in UTe<sub>2</sub>

ORAL

Abstract

UTe2 has drawn considerable interest for its unconventional superconducting phase(s). Evidence suggests spin-triplet superconductivity, with magnetic fluctuations responsible for the pairing. A symmetry-based argument of how anisotropic magnetic interactions prefer particular symmetries of the pairing gap function [1] is provided. In this work, based on density-functional theory calculations and model calculations, we discuss possible forms of magnetic interactions in UTe2.
