We calculate the conductance spectra of a Co atom adsorbed on Cu(111), considering the Co $3d$ orbitals within a correlated multiple configurations model interacting through the substrate band with the Co $4s$ orbital, which is treated in a mean-fiel

Final projectile charge states are experimentally and theoretically analyzed after ${\mathrm{H}}^{+}$ ions collide with a ${\mathrm{C}}_{60}$ monolayer deposited on Cu(111) with an ample range of incoming energies (2--8 keV) in the low-energy regime.

In this work we study the frontal collision of protons with the carbon atoms of a graphene surface with a low coverage of adsorbed potassium. It is aimed at the analysis of the effect of the adsorbates in both charge exchange and electron emission pr

In the present work, we propose an ionic Hamiltonian for describing the interaction of graphene with an adsorbed Co atom. In this approach, the electronic correlation effects, related to the many d orbitals involved in the interaction, are taken into

Charge-exchange processes in collisions between H+ projectiles and a three-monolayer C60 film grown on Cu(111) are experimentally and theoretically analyzed for a wide range of energies (2?8 keV) in the low-energy regime. The negative, positive, and

In this work we study the charge exchange process in the scattering of protons by potassium atoms adsorbed on a graphene surface in a low coverage limit. Both, the projected density of states on the alkaline atom site and the final charge states of t
An ionic Hamiltonian based on the first Hund rule applied to transition metal atoms is reviewed and discussed in detail. The tunneling current between a STM-tip and a transition metal atom is analyzed by means of that Hamiltonian combined with an eff

We found an error in the mathematical formulation of the finite-U model [19] that we used in our paper to describe the neutral fractions measured when Sr+ ions collide with a gold surface [4,5]. The error is connected to boundary conditions, such as

Kondo effects in individual atoms, molecular magnets or quantum dotshave received a lot of attention. Systems with two units, like double quantum dotsor two atoms, have also attracted some attention due to the interplay between thepossible coupling b
