A topological flux trap: Majorana bound states at screw dislocations
Stefan Rex, Roland Willa
The engineering of non-trivial topology in superconducting heterostructures is a very challenging task. Reducing the number of components in the system would facilitate the creatio…
Majorana modes in emergent-wire phases of helical and cycloidal magnet-superconductor hybrids
Stefan Rex, Igor V. Gornyi, Alexander D. Mirlin
Noncollinear magnetism opens exciting possibilities to generate topological superconductivity. Here, we focus on helical and cycloidal magnetic textures in magnet-superconductor hy…
Majorana bound states in magnetic skyrmions imposed onto a superconductor
Stefan Rex, Igor V. Gornyi, Alexander D. Mirlin
We consider a superconducting film exchange-coupled to a close-by chiral magnetic layer and study how magnetic skyrmions can induce the formation of Majorana bound states (MBS) in…
Magnon-induced superconductivity in a topological insulator coupled to ferro- and antiferromagnetic insulators
Henning G. Hugdal, Stefan Rex, Flavio S. Nogueira +1
We study the effective interactions between Dirac fermions on the surface of a three-dimensional topological insulator due to the proximity coupling to the magnetic fluctuations in…
Surface instability in nodal noncentrosymmetric superconductors
Carsten Timm, Stefan Rex, P. M. R. Brydon
We study the stability of topologically protected zero-energy flat bands at the surface of nodal noncentrosymmetric superconductors, accounting for the alteration of the gap near t…
