Phase-Controlled Topological Superconductivity

Invited

Abstract

This talk will explore alternative routes to generating Majorana zero modes, finding similarities between Majorana modes in vortex cores of 2D and 3D topological superconductors and schemes based on one-dimensional semiconductor-superconductor hybrids in a strong Zeeman field. Phase winding in vortices and full-shell nanowies has a 2D analog as well, which is phase control across an SNS junction, which in the presence of spin-orbit coupling and Zeeman field, also generates leads to topological superconductivity. Results from recent experiments will be discussed in the context of this unified picture.
