Charge transfer dynamics in atom scattering on atoms adsorbed on metal surface: Effect of electron correlations

Abstract

The time-dependent Anderson–Newns Hamiltonian with spin-dependent effective atom energy levels calculated within the Hartree–Fock approximation is used to study the occupation numbers of the atom scattered on another atom (adatom) adsorbed on the metal surface. The calculations are performed using the evolution operator approach. The memory effect of the initial spin polarisation of the scattered atoms is analysed for a broad class of parameters characterising the considered system.
