Topological superconductivity in artificial heterostructures

Abstract

In this thesis we will design an artificial heterostructure between a conventional s-wave superconductor with strong spin-orbit coupling and non-collinear magnets. We evaluate under which conditions Majorana edge states can form and obtain the topological phase diagram. For two-dimensional interfaces we additionally extract the spontaneous surface current resulting from the chiral edge states. We investigate these properties using both analytical methods as well as numerical tight-binding calculations.
