Descrição
Resumo:Theoretical approaches used here and their additional results including time-dependent density functional theory (TDDFT) calculations for the cylinder dimer; optically induced electron currents for 1, 2, and 6 nm gaps; additional results on the analysis of the quiver motion and CEP dependence of electron transfer; evaluation of energies of the transferred electrons from the TDDFT results; potential barrier in the gap; role of the image potential; possibility to account for its effect by performing the TDDFT calculations with lower work function of the metal; TDDFT results for jellium metal with a work function of gold; effect of the symmetry breaking on the optically induced electron transport with an example of a dc bias applied across the gap; wave packet propagation calculations of the optically induced electron transport in a one-dimensional (1D) model system considering a single active electron; CEP dependence of the electron transport calculated with WPP; simple man’s model analysis of the electron energy spectra; analytical strong field model and semiclassical electron trajectories; and effect of the plasmon ringing.
