Topological superconductivity in full-shell nanowires: numerical results and phase diagrams

ORAL

Abstract

We investigate numerically the Majorana topological phase appearing in semiconductor nanowires with a full superconducting shell. We consider both toy models and more realistic models where the electrostatic profile in the semiconducting core is computed self-consistently and the semiconductor and superconductor are treated on equal footing in the strong coupling regime. The topological phase diagram is computed for different core radii. This talk is a continuation of the previous talk on the same topic by R.M. Lutchyn.
