Majorana zero modes in one- and two-dimensional magnet-superconductor hybrid systems — •Stephan Rachel — School of Physics, University of Melbourne, Parkville, VIC 3010, Australia

Majorana zero modes, exotic quasiparticles in topological superconductors, are considered as the fundamental building blocks of future fault-tolerant quantum computers. The list of candidate materials is, however, short. Magnet-superconductor hybrid (MSH) systems represent one of the most promising platforms for topological superconductivity: magnetic atoms are placed on the surface of a conventional superconductor with spin-orbit coupling, leading to a topologically non-trivial system. Here we report recent theoretical progress on one- and two-dimensional MSH systems, and discuss them in the light of the latest experiments. By combining ab initio modeling and toy-model calculations on the theoretical side with atom-manipulation techniques via STM on the experimental side, we are getting closer to a complete understanding of Majorana zero modes in MSH systems.
