Plasmon-assisted chemistry is the result of a complex interplay between electromagnetic
near fields, heat and charge transfer on the nanoscale. The disentanglement of their roles is …

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

We present the development of the first ultrafast transmission electron microscope (UTEM)
driven by localized photoemission from a field emitter cathode. We describe the …

2D Ti3C2 T x MXenes were recently shown to exhibit intense surface plasmon (SP)
excitations; however, their spatial variation over individual Ti3C2 T x flakes remains …

This review provides a broad overview of the studies and effects of nonlocal response in
metallic nanostructures. In particular, we thoroughly present the nonlocal hydrodynamic …

Quantum tunneling between two plasmonic resonators links non-linear quantum optics with
terahertz nanoelectronics. Direct observation of and control over quantum plasmon …

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 …

This tutorial review presents an overview of theoretical methods for predicting and
understanding the optical response of gold nanoparticles. A critical comparison is provided …

The recent prediction and subsequent creation of electron vortex beams in a number of
laboratories occurred after almost 20 years had elapsed since the recognition of the physical …

Abstract Bound-states-in-the-continuum (BIC) is an emerging concept in nanophotonics with
potential impact in applications, such as hyperspectral imaging, mirror-less lasing, and …
