Periodic Reporting for period 4 - HITSUPERJU (Higher-dimensional topological solids realized with multiterminal superconducting junctions)
Période du rapport: 2021-02-01 au 2021-07-31
In conclusion, we have proven the potential of multi-terminal superconducting nanostructures as nanodevices. The field is rich with very interesting theoretical ideas and proposals, that are ready for experimental realization.
We have proposed several novel device setups: spin-Weyl quantum unit that is a non-trivial combination of spin and Andreev qubit, Weyl point based minimal spintronic device ,holonomic quantum computation setup based on discovery of Weyl disks.
Concentrating on the experimentally realized setups, we have addressed superconductor-seminconductor nanowires that are now in focus of experimental attention in view of Majorana applications. As a highlight, we propose a scheme to perform braiding and all other unitary operations with Majorana modes in 1D wire (rather than in 2D) that is solely based on resonant manipulation. We have proven the emergence of Weyl points in these topological nanowires and investigated the non-trivial microscopic mechanisms of the Andreev states overlap.
