Impurity clusters and localization of nodal quasiparticles in \emph{d}-wave superconductors
Yu. G. Pogorelov, M. C. Santos, V. M. Loktev
The long disputed issue of the limiting value of quasiparticle density of states $\r(0) = \r (\e \to 0)$ in a \emph{d-}wave superconductor with impurities (\emph{vs} its linear van…

Effects of extended impurity perturbation in d-wave superconductor
Yu. G. Pogorelov, M. C. Santos
We describe the effects of electronic perturbation distributed on nearest neighbor sites to the impurity center in a planar \textit{d}-wave superconductor, in approximation of circ…
