Inelastic scattering off magnetic impurities in a spin-chiral two-dimensional electron gas, e.g., the Rashba system, is shown to generate topological changes in the spin texture of the electron waves emanating from the scattering center. While elastic scattering gives rise to a purely in-plane spin texture for an in-plane magnetic scattering potential, out-of-plane components emerge upon activation of inelastic scattering processes. This property leads to a possibility to make controlled…

Electron Paramagnetic Resonance of Single Magnetic Moment on a Surface
TLDR
This work addresses electron spin resonance of single magnetic moments in a tunnel junction using time-dependent electric fields and spin-polarized current to explain the absence of an electronspin resonance for a half integer spin, in contrast with the strong signal observed for an integer spin.
A new view on the origin of zero-bias anomalies of Co atoms atop noble metal surfaces
TLDR
This work addresses systematically zero-bias anomalies detected by scanning tunneling spectroscopy on Co atoms deposited on Cu, Ag and Au(111) substrates, and unveils a new many-body feature, the spinaron, resulting from the interaction of electrons and spin-excitations localizing electronic states in a well defined energy.

Transverse Transport in Two-Dimensional Relativistic Systems with Nontrivial Spin Textures.
TLDR
The generally accepted expression of transverse resistivity in magnetic systems that host skyrmions, given by the linear superposition of the ordinary, the anomalous, and the topological Hall effect, is incomplete and must be amended by an additional term, the "noncollinear" Hall effect (NHE).
