Query: Strong localization of Majorana end states in chains of magnetic adatoms   A recent experiment [Nadj-Perge et al., Science 346, 602 (2014)] gives
possible evidence for Majorana bound states in chains of magnetic adatoms
placed on a superconductor. While many features of the observed end states are
naturally interpreted in terms of Majoranas, their strong localization remained
puzzling. We consider a linear chain of Anderson impurities on a superconductor
as a minimal model and treat it largely analytically within mean-field theory.
We explore the phase diagram, the subgap excitation spectrum, and the Majorana
wavefunctions. Owing to a strong velocity renormalization, the latter are
localized on a scale which is parametrically small compared to the coherence
length of the host superconductor.
