      abstract     = {Multiband effects in hybrid structures provide a rich
                      playground for unconventional superconductivity. We combine
                      two complementary approaches based on density-functional
                      theory (DFT) [1] and effective low-energy model theory in
                      order to investigate the proximity effect in a Rashba
                      surface state in contact with an s-wave superconductor [2].
                      We discuss these synergistic approaches and combine the
                      effective model and DFT analysis at the example of a Au/Al
                      heterostructure. This allows us to predict finite-energy
                      superconducting pairing due to the interplay of the Rashba
                      surface state of Au, and hybridization with the electronic
                      structure of superconducting Al. We investigate the nature
                      of the induced superconducting pairing, and we quantify its
                      mixed singlet-triplet character. Our findings demonstrate
                      general recipes to explore real material systems that
                      exhibit interorbital pairing away from the Fermi energy.This
