Time-resolved electrical detection of chiral edge vortex braiding

SciPost Physics, vol. 8

Abstract

A 2\pi 2 π phase shift across a Josephson junction in a topological superconductor injects vortices into the chiral edge modes at opposite ends of the junction. When two vortices are fused they transfer charge into a metal contact. We calculate the time dependent current profile for the fusion process, which consists of {\pm e/2} ± e / 2 charge pulses that flip sign if the world lines of the vortices are braided prior to the fusion. This is an electrical signature of the non-Abelian exchange of Majorana zero-modes.
