Kondo physics of magnetic adatoms on metallic surfaces when the onset of the surface conduction density of states crosses the Fermi level
J. Fernández, P. Roura-Bas
We study the role of the onset of Shockley states, , belonging to (111) surfaces of Cu, Ag and Au in the Kondo effect when a magnetic impurity is deposited on them. When …
Quantifying the leading role of the surface state in the Kondo effect of Co/Ag(111)
M. Moro-Lagares, J. Fernández, P. Roura-Bas +3
Using a combination of scanning tunneling spectroscopy and atomic lateral manipulation, we obtained a systematic variation of the Kondo temperature () of Co atoms on A…
Width of the charge-transfer peak in the SU(N) impurity Anderson model and its relevance to non-equilibrium transport
J. Fernández, F. Lisandrini, P. Roura-Bas +2
We calculate the width and intensity of the charge-transfer peak (the one lying at the on-site energy ) in the impurity spectral density of states as a functi…
Kondo temperature when the Fermi level is near a step in the conduction density of states
J. Fernández, A. A. Aligia, P. Roura-Bas +1
The (111) surface of Cu, Ag and Au is characterized by a band of surface Shockley states, with constant density of states beginning slightly below the Fermi energy. These states as…
Valence fluctuations in a lattice of magnetic molecules: application to iron(II) phtalocyanine molecules on Au(111)
J. Fernández, A. A. Aligia, Alejandro M. Lobos
We study theoretically a square lattice of the organometallic Kondo adsorbate iron(II) phtalocyanine (FePc) deposited on top of Au(111), motivated by recent scanning tunneling micr…
Numerical results for the Edwards-Anderson spin-glass model at low temperature
J. F. Fernández, J. J. Alonso
We have simulated Edwards-Anderson (EA) as well as Sherrington-Kirkpatrick systems of L^3 spins. After averaging over large sets of EA system samples of 3 =< L =< 10, we obtain acc…
