      abstract     = {When a foreign atom is placed on a surface of a metal, the
                      surrounding sea of electrons responds by screening the
                      additional charge leading to oscillations or ripples. On
                      surfaces, those electrons are sometimes confined to
                      two-dimensional surface states, whose spin-degeneracy is
                      lifted due to the Rashba effect arising from the spin-orbit
                      interaction of electrons and the inversion asymmetric
                      environment. It is believed that at least for a single
                      adatom scanning tunneling microscopy measurements are
                      insensitive to the Rashba splitting; i.e., no signatures in
                      the charge oscillations will be observed. Resting on
                      scattering theory, we demonstrate that, if magnetic, one
                      single adatom is enough to visualize the presence of the
                      Rashba effect in terms of an induced spin magnetization of
                      the surrounding electrons exhibiting a twisted spin texture
                      described as superposition of two Skyrmionic waves of
                      opposite chirality.},
