Supercurrent in superconductor-topological insulator-superconductor junctions with vortices
ORAL
Abstract
Topological insulator-superconuctor (TI-SC) heterostructures are a promising platform for creation and manipulation of Majorana Zero Modes (MZMs). Vortices in such heterostructures are theorized to bind MZMs, while SC-TI-SC junctions can potentially be used to fuse MZMs. In this work, we numerically investigate the relative strength of the trivial 2π and topological 4π contributions to the supercurrent in SC-TI-SC junctions with vortices, and using these results develop a MZM fusion protocol in such systems.
