    Topological superconductivity from ferromagnetic impurity chains on NbSe2

    Résumé : Recent experiments have resolved Yu-Shiba-Rusinov bound states induced by magnetic impurities (atoms or molecules) on NbSe2 superconductors. In our work, we show that it is possible to generate Majorana bound states localized at the ends of chains of ferromagnetic impurities on top of NbSe2. The robustness of topological phases is analyzed as a function of coupling strength between substrate and impurity, the orientation of the impurity chains on the superconductor, and the impurity spin direction.
