A novel optical effect can be observed in a thin gold foil due to the excitation of surface plasmons which permits a form of all-optical modulation at low pulse rates. Modulated excitation of surface plasmons by infrared photons is shown to couple to

Effective energy-loss functions were derived for oxygen-adsorbed amorphous silicon surfaces from a reflection electron energy-loss spectroscopy analysis based on the extended Landau theory. This study has revealed that the intensity of the surface-pl

It is well known that the hydrodynamical model of the electron gas is suitable when the electron density can be considered as the fundamental quantity, small wavelength effects being less important. This is the case when the electron gas is excited b

We present a nonlinear modulation scheme based on coupling between optically excited surface plasmons in a thin gold film and the heating of the film by a pulsed direct current, and also for the reverse process. The reflected surface-plasmon excitati

A survey is presented of the theoretical status in understanding some nonlinear aspects of charged particle interactions in matter. In particular, a diagrammatic analysis of the many-body interactions between a moving particle and the electron gas is

A many-body perturbation-theoretic calculation of the double-plasmon excitation in an electron gas is presented, using Feynman diagrams. The low-q limit of the inverse mean free path for this second order process is evaluated in the random-phase-appr

The surface scattering of kilovolt-energy ions and atoms at glancing-incidence angles has contributed substantially to knowledge of elementary electronic excitations in the interface region. We consider the influence of inelastic exchange of mechanic

Experimental work by Shea and Compton suggests that ${\mathrm{Ag}}^{+}$ ions emitted from a roughened Ag surface irradiated by a nanosecond or picosecond laser beam may absorb the full energy of the Ag surface plasmon (SP). We have modeled this proce
