| 520 | _ | _ | |a Materials that combine magnetism, spin-orbit interaction and conventional s-wave superconductivity are a suitable platform to study Yu-Shiba-Rusinov (YSR) states [1-3] and Majorana zero modes (MZM) [4], that can be used as building blocks of fault-tolerant topological qubits.Recently, STM experiments for Gd chains on Nb(110) surface showed indication of MZMs at the ends of the chains [5]. To better understand the nature of those modes, we implemented the Bogoliubov-de Gennes (BdG) formalism in the juKKR impurity code [6] that allows the material-specific description of defects in superconductors from first principles, and applied it to Gd adatom nanostructures placed on the superconducting Nb(110) surface. We analyze the YSR states arising from the coupling of the magnetic Gd atoms and investigate their dependence on the geometry of the nanocluster and its magnetic ordering.This work was funded by the DFG through Germany’s Excellence Cluster ML4Q (EXC 2004/1 - 390534769).[1] L.
