Abstract

Result of a fully relativistic local density band calculation for UPt₃, which are in excellent agreement with photoemission experiments by Arko et al., are used to study the origin of its observed superconductivity with a conventional approach - the rigid ion approximation and McMillan's theory. We find a highly anisotropic electron-phonon interaction which induces strong superconducting gap anisotropy. The model developed leads to several predictions and a consisted explanation of the unusual properties of UPt₃.
