Role of Excited States in Resonant Charge Transfer during Li Backscattering from MoS: A Multi-Orbital Theoretical Study
Thomas A. Balsamo, Faustino G. Ibarlucea, Marcelo A. Romero
We present a theoretical investigation of resonant charge transfer in low-energy Li ions backscattered from a MoS surface, focusing on the influence of excited projectile s…

Spectral evolution of the SU(4) Kondo effect from the single impurity to the two-dimensional lattice
Alejandro M. Lobos, Marcelo Romero, Armando A. Aligia
We describe the evolution of the SU(4) Kondo effect as the number of magnetic centers increases from one impurity to the two-dimensional (2D) lattice. We derive a Hubbard-Anderson…

Scanning tunneling microscopy of adsorbed molecules on metalic surfaces for nearly localized atomic states
M. Romero, A. A. Aligia
We consider a Hubbard-Anderson model which describes localized orbitals in five different sites hybridized both among themselves and with a continuum of extended states. A square p…
