Progress in electron-beam spectroscopies has recently enabled the study of optical
excitations with combined space, energy and time resolution in the nanometre …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Silver nanoparticles (AgNPs) show different physical and chemical properties compared to
their macroscale analogs. This is primarily due to their small size and, consequently, the …

Free electron beams such as those employed in electron microscopes have evolved into
powerful tools to investigate photonic nanostructures with an unrivaled combination of …

When light interacts with a metal nanoparticle (NP), its conduction electrons can be driven
by the incident electric field in collective oscillations known as localized surface plasmon …

MNPBEM is a Matlab toolbox for the simulation of metallic nanoparticles (MNP), using a
boundary element method (BEM) approach. The main purpose of the toolbox is to solve …

Within the last 30 years, electron energy-loss spectroscopy (EELS) has become a standard
analytical technique used in the transmission electron microscope to extract chemical and …

This review discusses how low-energy valence excitations created by swift electrons can
render information on the optical response of structured materials with unmatched spatial …

The remarkable optical properties of metal nanoparticles are governed by the excitation of
localized surface plasmon resonances (LSPRs). The sensitivity of each LSPR mode, whose …

We push the fabrication limit of gold nanostructures to the exciting sub-nanometer regime, in
which light–matter interactions have been anticipated to be strongly affected by the quantum …
