Impurity scattering in f-wave superconductor UPt_3

摘要

We study theoretically the effect of impurity scattering in f-wave (or E_(2u)) superconductors. The quasi-particle density of states of f-wave superconductor is very similar to the one for d-wave superconductor as in hole-doped high T_c cuprates. Also in spite of anisotropy in Δ(k-circumflex), both the reduced superfluid density and the reduced electronic thermal conductivity is completely isotropic.
