| Abstract: | We report new theoretical results and analysis for the transport properties of superconducting UPt3 based on the leading models for the pairing symmetry. We use Fermi surface data and the measured inelastic scattering rate to show that the low-temperature thermal conductivity and transverse sound attenuation in the A- and B-phase of UPt3 are in excellent agreement with pairing states belonging to the two-dimensional orbital E2u representation. |
