# Majorana quasiparticles of inhomogeneous Rashba chain

@inproceedings{Maka2016MajoranaQO, title={Majorana quasiparticles of inhomogeneous Rashba chain}, author={Maciej M Maśka and Anna Gorczyca-Goraj and Jakub Tworzydło and Tadeusz Domański}, year={2016} }

We investigate the inhomogeneous Rashba chain coupled to a superconducting substrate, hosting the Majorana quasiparticles near its edges. We discuss its subgap spectrum and study how robust are the zero-energy quasiparticles against the diagonal and off-diagonal disorder. Studying the Z2 topological invariant we show that disorder induced transition from the topologically non-trivial to trivial phases is manifested by characteristic features in the spatially-resolved quasiparticle spectrum at…

The key finding is that multiband occupancy not only lifts the stringent constraint of one-dimensionality but also allows one to have higher carrier density in the nanowire, and as such multisubband nanowires are better suited for observing the Majorana particle.

It is shown that the probability distribution of ε(0) is log normal in the limit of large L, whereas the distribution of the lowest-lying bulk energy levelε(1) has an algebraic tail at small δ(1), which has implications for the speed at which a topological quantum computer can be operated.
