Disorder Suppression in Topological Semiconductor-Superconductor Junctions
The study investigates how disorder in a bulk superconductor affects quasiparticles scattering into a topological superconductor via a Josephson junction. Using random-matrix theory, the research shows that disorder scattering can be suppressed when there is a mismatch between the Fermi wavelengths of the semiconductor and the superconductor. This suppression is significant for maintaining topological superconductivity.
