Abstract
The changes of the nonlinear optical response by single atoms adsorbed on free-electron-like metal surfaces are calculated in the low-freque ncy limit. Density-functional theory and an extension of the atom+jell ium chemisorption model by Lang and Williams allowing for the presence of an external static field is used. The results enable a detailed di scussion of the mechanisms responsible for the characteristic effects of adsorbates on second-harmonic generation as evident from recent exp eriments on metal surfaces.
