Topological transitions in electronic spectra: Crossover between Abrikosov and Josephson vortices

A. V. Samokhvalov, V. D. Plastovets, A. S. Mel'nikov

The electronic structure of a vortex line trapped by a planar defect in a type-II superconductor is analyzed within the Bogoliubov-de Gennes theory. The normal reflection of electr…
