Controlling Majorana hybridization in magnetic chain-superconductor systems
Oladunjoye A. Awoga, Ioannis Ioannidis, Archana Mishra +3
We propose controlling the hybridization between Majorana zero modes at the ends of magnetic adatom chains on superconductors by an additional magnetic adatom deposited close by. B…
