Josephson tunneling through a Yu-Shiba-Rusinov state: Interplay of -shifts in Josephson current and local superconducting order parameter
Andreas Theiler, Christian R. Ast, Annica M. Black-Schaffer
An impurity hosting a magnetic moment coupled to a conventional -wave superconductor gives rise to so-called Yu-Shiba-Rusinov (YSR) states with energies inside the superconducti…

Temperature dependent energy gap for Yu-Shiba-Rusinov states at the quantum phase transition
Andreas Theiler, Christian R. Ast, Annica M. Black-Schaffer
Motivated by recent experiments, which allow for fine tuning of the effective magnetic interaction between the impurity and the superconductor, we investigate the regime around the…

Majorana bound state localization and energy oscillations for magnetic impurity chains on conventional superconductors
Andreas Theiler, Kristofer Björnson, Annica M. Black-Schaffer
We study a chain of magnetic impurities on a conventional superconductor with spin-orbit coupling, treating the superconducting order fully self-consistently. We find and quantify…
