Solid state Stern-Gerlach spin-splitter for magnetic field sensoring, spintronics, and quantum computing
Kristofer Björnson, Annica M. Black-Schaffer
We show that the edge of a two-dimensional topological insulator can be used to construct a solid state Stern-Gerlach spin-splitter. By threading such a Stern-Gerlach apparatus wit…
Spin-polarized edge currents and Majorana fermions in one- and two-dimensional topological superconductors
Kristofer Björnson, Sergey. S. Pershoguba, Alexander. V. Balatsky +1
We investigate the persistent currents, spin-polarized local density of states, and spectral functions of topological superconductors constructed by placing ferromagnetic impuritie…
Currents induced by magnetic impurities in superconductors with spin-orbit coupling
Sergey S. Pershoguba, Kristofer Björnson, Annica M. Black-Schaffer +1
We show that superconducting currents are generated around magnetic impurities and ferromagnetic islands proximity-coupled to superconductors with finite spin-orbit coupling. Using…
Probing vortex Majorana fermions and topology in semiconductor-superconductor heterostructures
Kristofer Björnson, Annica M. Black-Schaffer
We investigate the local density of states, spectral function, and superconducting pair amplitudes for signatures of Majorana fermions in vortex cores in ferromagnetic and spin-orb…
