Properties of Majorana Fermions in a Planar Josephson Junction — •Aidan Wastiaux and Falko Pientka — Max-Planck Institute for the Physics of Complex Systems, Dresden

As topologically protected quasi-particles, Majorana fermions are of great interest for the future of quantum information. The most promising experimental platform for Majorana states is based on heterostructures of superconductors and semiconductor nanowires in a magnetic field. In Ref. [1], an alternative platform based on a 2D Josephson junction in a 2d semiconductor with spin-orbit coupling has been proposed. The topological phase can be controlled by an in-plane magnetic field and the phase difference across the junction. Motivated by recent experimental progress [2], we investigate properties of the topological phase and Majorana states in this platform.
