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 …

Plasmonic phenomena in metals are commonly explored within the framework of classical
electrodynamics and semiclassical models for the interactions of light with free-electron …

Electron energy-loss spectroscopy can be used for detailed spatial and spectral
characterization of optical excitations in metal nanoparticles. In previous electron energy …

Historically, the field of plasmonics has been relying on the framework of classical
electrodynamics, with the local-response approximation of material response being applied …

Requirements of integrated photonics and miniaturisation of optical devices demand
efficient nonlinear components not constrained by conventional macroscopic nonlinear …

The tremendous growth of the field of plasmonics in the past twenty years owes much to the
pre-existence of solid theoretical foundations. Rather than calling for the introduction of …

Quantum effects of plasmonic phenomena have been explored through ab initio studies, but
only for exceedingly small metallic nanostructures, leaving most experimentally relevant …

The surface-response formalism (SRF), where quantum surface-response corrections are
incorporated into the classical electromagnetic theory via the Feibelman parameters, serves …

The optical properties of metallic nanoparticles with nanometre dimensions exhibit features
that cannot be described by classical electrodynamics. In this quantum size regime, the near …

Understanding light interaction with metallic structures provides opportunities of
manipulation of light, and is at the core of various research areas including terahertz (THz) …
