Theory of surface plasmons and surface-plasmon polaritons [PDF]
Reports on Progress in Physics, 2006 Collective electronic excitations at metal surfaces are well known to play a key role in a wide spectrum of science, ranging from physics and materials science to biology. Here we focus on a theoretical description of the many-body dynamical electronic response of solids, which underlines the existence of various collective electronic excitations at ...

Surface effects on bulk plasmons [PDF]
Physical Review B, 1993 We discuss the effects of surfaces on bulk plasma oscillations in a metallic film of thickness $L$. The leading corrections to the plasma frequencies due to the surfaces are proportional to $L^{-1}$. dispersion relation of bulk modes, $ω=ω_p[1+α(q^2/k_F^2)] $, where the allowed $q$-values are $q^{(n)}=(nπ/\overline L)$, $\overline L\equiv L-2d_b$, and $

Surface Plasmon Radiation Forces [PDF]
Physical Review Letters, 2006 We report the first experimental observation of momentum transfer from a surface plasmon to a single dielectric sphere. Using a photonic force microscope, we measure the plasmon radiation forces on different polystyrene beads as a function of their distance from the metal surface.
