Effect of Order-Parameter Suppression on Scattering by Isolated Impurities in Asymmetric Bands
W. A. Atkinson, P. J. Hirschfeld, A. H. MacDonald
Abstract
The single-impurity problem in d-wave superconductors with asymmetric bands is discussed. The effect of local order parameter suppression near the impurity is to shift the quasiparticle resonance. Contrary to previous work [A. Shnirman et al., Phys. Rev. B 60, 7517 (1999)] we find that the direction of the shift is not universally towards the strong scattering limit.
