Impurity bound states in fully gapped -wave superconductors with subdominant order parameters
Mahdi Mashkoori, Kristofer Björnson, Annica M. Black-Schaffer
Impurities in superconductors and their induced bound states are important both for engineering novel states such as Majorana zero-energy modes and for probing bulk properties of t…
Superconducting order parameter -phase shift in magnetic impurity wires
Kristofer Björnson, Alexander. V. Balatsky, Annica M. Black-Schaffer
It has previously been found that a magnetic impurity in a conventional -wave superconductor can give rise to a local -phase shift of the superconducting order parameter. By…
Majorana fermions at odd junctions in a wire network of ferromagnetic impurities
Kristofer Björnson, Annica M. Black-Schaffer
We consider a wire network of ferromagnetic impurities on the surface of an -wave superconductor with strong Rashba spin-orbit interaction. Within the topological phase, zero-en…
