Long-term magnetic stability of single atoms: a group-theoretical viewpoint — •Timofey Balashov, Christopher Bresch, and Wulf Wulfhekel — Physikalisches Institut, Karlsruhe Institute of Technology, Wolfgang-Gaede-Str. 1, 76131 Karlsruhe, Germany

The recent observation of extremely long lifetimes in single Holmium atoms on Pt(111) [1] can be explained by a careful consideration of the inherent symmetries of the system; namely, the rotation symmetry of the adsorption site, the total angular momentum symmetry of the atom and the time reversal symmetry of the whole system. Here, we describe the model in more detail and demonstrate its robustness against perturbations. We also apply this model to other rare earths to identify promising systems for future research.
