Majorana Quasiparticles Are Robust and Controllable (image) Princeton University Share Print E-Mail Caption A scanning tunneling microscope (STM) was used to visualize Majorana quasiparticles (green peaks) occurring at the ends of topological edge channels (yellow regions) at the atomic steps of a bismuth thin film grown on a superconducting surface. Small magnetic clusters are seen as small bumps decorating the corner of these edges. At the interfaces between the magnetic clusters and the edge channel, experiments detected robust Majorana quasiparticles, but only when the cluster magnetization points along the channel.
