Large spectral gap and impurity-induced states in a two-dimensional Abrikosov vortex
A. A. Bespalov, V. D. Plastovets
We study the subgap spectrum of a 2D Abrikosov vortex in an s-wave superconductor in the absence and presence of a point impurity. By solving the Eilenberger equations without impu…

Impurity-induced subgap states in superconductors with inhomogeneous pairing
A. A. Bespalov
We study subgap states induced by a single impurity in an s-wave superconductor with suppressed pairing. For concreteness, we consider a bulk superconductor containing a normal sph…
