      abstract     = {Magnetic skyrmions are spin swirling solitonic defects that
                      can play a major role in information technology. Their
                      future in applications and devices hinges on their efficient
                      manipulation and detection. Here, we explore from ab-initio
                      their nature as magnetic inhomongeities in an otherwise
                      unperturbed magnetic material, Fe layer covered by a thin Pd
                      film and deposited on top of Ir(111) surface. The presence
                      of skyrmions triggers scattering processes, from which
                      Friedel oscillations emerge. The latter mediate interactions
                      among skyrmions or between skyrmions and other potential
                      surrounding defects. In contrast to their wavelengths, the
                      amplitude of the oscillations depends strongly on the size
                      of the skyrmion. The analogy with the scattering-off atomic
                      defects enables the assignment of an effective scattering
                      potential and a phase shift to the skyrmionic particles,
                      which can be useful to predict their behavior on the basis
                      of simple scattering frameworks. The induced charge ripples
                      can be utilized for a noninvasive all-electrical detection
                      of skyrmions located on a surface or even if buried a few
                      nanometers away from the detecting electrode.},
