Energy spectrum of superconductors with defects having spherical and cylindrical symmetry of their interaction potential with conduction electrons

M. M. Gvozdikov, I. I. Fal'ko


Abstract: Spatial behaviour of the ordering parameter in superconductors with defects is considered. Two cases are investigated: a) the point defect, for which the potential of interaction with conductivity electrons is rotationally invariant; b) the linear defect, for which the potential of interaction with conductivity electrons is invariant under the rotations with respect to the defect axis.
