      abstract     = {The interplay of superconductivity and strong spin-orbit
                      coupling has gained a lot of attention in recent year. For
                      instance, it was realized that Cooper pairing can occur
                      intrinsically away from the Fermi surface in j=3/2
                      superconductors with strong spin-orbit coupling [Phys. Rev.
                      Research 4, L012017 (2022)]. In this work, we present a
                      theoretical study of the proximity-induced superconducting
                      coupling in a Rashba surface state due to its contact to an
                      s-wave superconductor.We combine theoretical modelling and
                      ab initio Bogolibov-de Gennes simulations [PRB 105, 125143
                      (2022)] using the JuKKR density functional theory code
                      [https://jukkr.fz-juelich.de]. We investigate the proximity
                      effect in the Rashba surface state at the interface between
                      Al(111) and Au(111) that arises from the combination of
                      strong spin-orbit coupling in Au and broken symmetry at the
                      interface. We discuss how inter-orbital pairing can occur at
                      finite energies away from the Fermi level under an external
                      magnetic field and comment on the pairing symmetry in the
                      proximity-induced coupling of the Rashba surface state.},
