      abstract     = {Magnetic skyrmions are prime candidates for future
                      spintronic devices. However, incorporating them as
                      information carriers hinges on their interaction with
                      defects ubiquitous in any device. Here we map from
                      first-principles, the energy profile of single skyrmions
                      interacting with single-atom impurities, establishing a
                      generic shape as function of the defect’s electron
                      filling. Depending on their chemical nature, foreign 3d and
                      4d transition metal adatoms or surface implanted defects can
                      either repel or pin skyrmions in PdFe/Ir(111) thin films,
                      which we relate to the degree of filling of bonding and
                      anti-bonding electronic states inherent to the proximity of
                      the non-collinear magnetic structure. Similarities with key
                      concepts of bond theories in catalysis and surface sciences
                      imbue the universality of the shape of the interaction
                      profile and the potential of predicting its interaction. The
                      resulting fundamental understanding may give guidance for
                      the design of devices with surface implanted defects to
                      generate and control skyrmions.},
