Ultrathin dielectric gaps between metals can trap plasmonic optical modes with surprisingly
low loss and with volumes below 1 nm3. We review the origin and subtle properties of these …

The discovery of the enhancement of Raman scattering by molecules adsorbed on
nanostructured metal surfaces is a landmark in the history of spectroscopic and analytical …

The ability to confine light into tiny spatial dimensions is important for applications such as
microscopy, sensing, and nanoscale lasers. Although plasmons offer an appealing avenue …

Real-space grids are a powerful alternative for the simulation of electronic systems. One of
the main advantages of the approach is the flexibility and simplicity of working directly in real …

We present an ab initio study of the hybridization of localized surface plasmons in a metal
nanoparticle dimer. The atomic structure, which is often neglected in theoretical studies of …

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 …

The field of two-dimensional (2D) materials-based nanophotonics has been growing at a
rapid pace, triggered by the ability to design nanophotonic systems with in situ control …

Metallic nanostructures exhibit a multitude of optical resonances associated with localized

Metallic structures with nanogap features have proven highly effective as building blocks for
plasmonic systems, as they can provide a wide tuning range of operating frequencies and …

Electromagnetic field localization in nanoantennas is one of the leitmotivs that drives the
development of plasmonics. The near-fields in these plasmonic nanoantennas are …
