Abstract
Abstract Recently a number of nodal superconductors have been identified. These include high T c cuprate superconductors, the ones in Sr 2 RuO 4 , CeCoIn 5 , κ -(ET) 2 Cu(NCS) 2 , UPd 2 Al 3 , etc. The optical conductivity for E parallel to the conducting plane is the same for these nodal superconductors. Limiting our study to T = 0 K, we compute σ 1 ( ω ) and ωσ 2 ( ω ) in the presence of impurities. When the impurity scattering is in the unitary limit, σ 1 ( ω ) has a peak for ω / Δ ∼ 0.1–0.5. This may account for the peak seen by Basov et al. [D.N. Basov, B. Dabrowski, T. Timusk, Phys. Rev. Lett. 81 (1998) 2132] in Zn-substituted YBCO.
