Iron impurities in gold and silver: Comparison of transport measurements to numerical renormalization group calculations exploiting non-Abelian symmetries
M. Hanl, A. Weichselbaum, T. A. Costi +4
We consider iron impurities in the noble metals gold and silver and compare experimental data for the resistivity and decoherence rate to numerical renormalization group results. B…

Kondo decoherence: finding the right spin model for iron impurities in gold and silver
T. A. Costi, L. Bergqvist, A. Weichselbaum +8
We exploit the decoherence of electrons due to magnetic impurities, studied via weak localization, to resolve a longstanding question concerning the classic Kondo systems of Fe imp…
