abstract = {Interfacing superconductors with magnetic or topological
materials offers a playground where novel phenomena like
topological superconductivity, Majorana zero modes, or
superconducting spintronics are emerging [1]. In this work,
we discuss recent developments in the Kohn-Sham
Bogoliubov-de Gennes method, which allows to perform
material-specific simulations of complex superconducting
heterostructures on the basis of density functional theory
[2]. As a model system we study magnetically-doped Pb [3].
In our analysis we focus on the interplay of magnetism and
superconductivity. This combination leads to
Yu-Shiba-Rusinov (YSR) in-gap bound states at magnetic
defects and the breakdown of superconductivity at larger
impurity concentrations. Moreover, the influence of
spin-orbit coupling and on orbital splitting of YSR states
as well as the appearance of a triplet component in the
order parameter is discussed. These effects can be exploited
in S/F/S-type devices (S=superconductor, F=ferromagnet) in
the field of superconducting spintronics [1].---[1] R. Cai,
