    • We denote the wave vector at K (K′) point by K (K′): K = (2π/3a;, 2π/√3a) and K′ = (4π/3a; 0).

    • The constant term liner in u can be absorbed into the chemical potential and gives no contribution.

    • Exponentially small density of states ρ(0) at the chemical potential caused by weak impurity scattering in superconductors with line nodes was also shown by L. P. Gor'kov and P. A. Kalugin: Pis'ma Zh. Eksp. Teor. Fiz. 41 (1985) 208

    • note
    • The obtained conductivity is larger than that in ref. 12 by factor 2 because the spin degrees of freedom are considered here. Note also that the definition of Δ(ε) differs from that in ref. 12.
