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 Majorana states, 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…

TLDR
The results indicate that a purely p-wave or a dominant p- wave substrate are not good candidates to support either magnetic or scalar impurity topological Shiba chains.
Majorana spin in magnetic atomic chain systems
Magnetic atomic chains grown on top of conventional superconductors may form an interesting and promising platform for the study of Majorana zero modes. Despite the strong evidence already provided

Abstract We investigate theoretically a Fano interferometer composed by STM and AFM tips close to a Kitaev dimer of superconducting adatoms, in which the adatom placed under the AFM tip, encloses a
Controlled length-dependent interaction of Majorana modes in Yu-Shiba-Rusinov chains
Magnetic atoms on superconductors induce localized Yu-Shiba-Rusinov (YSR) bound states. The proposal that topological superconductivity and Majorana modes can be engineered in arrays of hybridizing

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

The hybridization of Yu-Shiba-Rusinov (YSR) states in dimers of magnetic impurities leads to molecularlike bonding and antibonding modes. In many-impurity systems, the interaction gives rise to YSR

TLDR
It is found that in the self-consistent solution, the average superconducting gap function over the adatom sites has a discontinuous drop with increasing exchange interaction at the same critical value where the topological phase transition occurs.

These experiments establish InAs/GaSb as a promising platform for the confinement of Majoranas into localized states, enabling future investigations of non-Abelian statistics and gate-tuning between edge-dominated and bulk-dominated regimes of superconducting transport.
