Magnetic domain walls for tunable Majorana devices
Daniel Hauck, Stefan Rex, Markus Garst
Identifying realistic platforms capable of controlled operations with Majorana bound states is a key challenge in the study of topological superconductivity. Among the most promisi…
Topological staggered field-electric effect with bipartite magnets
Stefan Rex, Flavio Nogueira, Asle Sudbø
We study the interface physics of bipartite magnetic materials deposited on a topological insulator. This comprises antiferromagnets as well as ferrimagnets and ferromagnets with m…
Topological magnetic dipolar interaction and non-local electric magnetization control in topological insulator heterostructures
Stefan Rex, Flavio S. Nogueira, Asle Sudbo
The magnetoelectric effect predicted in topological insulators makes heterostructures that combine magnetic materials and such insulators promising candidates for spintronics appli…
Non-local topological magnetoelectric effect by Coulomb interaction at a topological insulator-ferromagnet interface
Stefan Rex, Flavio Nogueira, Asle Sudbø
The interface between a topological insulator and a ferromagnetic insulator exhibits an interesting interplay of topological Dirac electrons and magnetism. As has been shown recent…
Tilting of the magnetic field in Majorana nanowires: critical angle and zero-energy differential conductance
Stefan Rex, Asle Sudbø
Semiconductor nanowires with strong spin-orbit coupling and proximity-induced s-wave superconductivity in an external magnetic field have been the most promising settings for appro…
