“…For particle trajectories inside the solid (z > 0), Eq. (9.13) reproduces the result first obtained by Nuñez et al [316]. Outside the solid, the energy loss is dominated by the excitation of surface plasmons at ω s .…”

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 metal surfaces, such as the conventional surface plasmon, multipole plasmons, and the recently predicted acoustic surface plasmon. We also review existing calculations, experimental measurements, and applications.

“…Similar calculations have been done using a simple dielectric model, 20 where only excitation of a low-energy two-dimensional (2D) plasmon was considered, or by using the hydrodynamic model, 21 where the wake potential in carbon nanotubes has been investigated. Here we are in the framework of more general theories established a long time ago to investigate the energy loss and wake potential of moving ions close to a solid surface 22 or the wake potential and self-energy of a particle moving near a metallic surface 23,24 by using simple plasmon-pole or semiclassical approximations. 25 In this work the response function and the induced potential are obtained using the first-principles time-dependent density functional theory (TDDFT) to calculate the dynamical response function and the energy-loss rate, where we include contributions of all electronic excitations up to 25 eV.…”

A propagator of the dynamically screened Coulomb interaction in the vicinity of a graphene monolayer is calculated using ground-state Kohn-Sham orbitals, and the imaginary part of this propagator is used to calculate the energy-loss rate of a static blinking point charge due to excitation of electronic modes in graphene. Energy loss calculated for all (Q,ω) modes gives intensities of electronic excitations, including plasmon dispersions in graphene, with low-energy two-dimensional (2D) and high-energy π 1 , π 2 , and π + σ plasmons. Plasmon energies are in good agreement with experimental results. This spectral analysis also enables us to study the contribution of each plasmon mode to the stopping power and potential induced by a point charge moving parallel to the graphene. We find the bow waves that in pristine graphene appear for higher velocities (v 2v F ) and predominantly originate from excitation of π plasmons. Doping induces extra features which appear for lower v ≈ v F velocities and predominantly originate from the excitation of 2D or Drude plasmons.
