In the last decades, the blossoming of experimental breakthroughs in the domain of electron energy loss spectroscopy (EELS) has triggered a variety of theoretical developments. Those have to deal with completely different situations, from atomically resolved phonon mapping to electron circular dichroism passing by surface plasmon mapping. All of them rely on very different physical approximations and have not yet been reconciled, despite early attempts to do so. As an effort in that direction…

QED theory of electron beam-induced electronic excitation and its effect on sputtering cross sections in 2D crystals

Many computational models have been developed to predict the rates of atomic displacements in two-dimensional (2D) materials under electron beam irradiation. However, these models often drastically

Optical polarization analogue in free electron beams

Fast electrons spectromicroscopies enable to measure quantitatively the optical response of excitations with unrivaled spatial resolution. However, due to their inherently scalar nature, electron

Quantum electrodynamics in the presence of dielectrics and conductors. II. Theory of dispersion forces

The different kinds of response functions introduced in a previous paper are used to calculate the dispersion forces. An exact expression for the interaction energy in a system of harmonic

Correlations in space and time and dynamical diffraction of high-energy electrons by crystals.

It is proved that if the energy of an electron is sufficiently high (E∼100 ReV), the problem of multiple elastic and inelastic scattering by a solid is entirely determined by two universal functions.

Cross density of states and mode connectivity: Probing wave localization in complex media

We introduce the mode connectivity as a measure of the number of eigenmodes of a wave equation connecting two points at a given frequency. Based on numerical simulations of scattering of

Dichroism in the interaction between vortex electron beams, plasmons, and molecules.

The transfer of orbital angular momentum between vortex electron beams and chiral samples, such as staircase plasmonic nanostructures and biomolecules, is studied to suggest a way of spatially resolving chiral optical excitations, including dark plasmons.

Spatial coherence in complex photonic and plasmonic systems.

This work demonstrates unambiguously the spatial squeezing of eigenmodes on disordered fractal metallic films, thus clarifying a basic issue in plasmonics.
