Title: Majorana bound states in S-TI-S lateral Josephson junctions
Abstract:
It is predicted that S-TI-S lateral Josephson junctions, fabricated by depositing electrodes of a conventional superconductor (S) on the surface of a topological insulator (TI), exhibit Majorana bound states (MBS) at locations in the junction where the phase difference is an odd-multiple of Pi There is evidence for this from the lifting of odd nodes in the critical current diffraction patterns and the observation of supercurrent features at magnetic fields where the MBS enter the junction. In this talk, I will talk progress on experiments on Nb-Bi2Se3-Nb junctions designed to probe the parity states of MBS pairs and the transitions between them via measurements of the critical current distribution and supercurrent fluctuations. These experiments, in conjunction with modeling will form the basis of a platform for creating, manipulating, and braiding MBS for quantum computing purpose.
