When a foreign atom is placed on a surface of a metal, the surrounding sea ofelectrons responds screening the additional charge leading to oscillations orripples. On surfaces, those electrons are sometimes confined to two-dimensionalsurface states, whose spin-degeneracy is lifted due to the Rashba effectarising from the spin-orbit interaction of electrons and the inversionasymmetric environment. It is believed that at least for a single adatomscanning tunneling microscopy measurements are insensitive to the Rashbasplitting i.e. no signatures in the charge oscillations will be observed.Resting on scattering theory, we demonstrate that, if magnetic, one singleadatom is enough to visualize the presence of the Rashba effect in terms of aninduced spin-magnetization of the surrounding electrons exhibiting a twistedspin texture described as superposition of two skyrmionic waves of oppositechirality.
