Light Coupling to Plasmonic Nanocavities
… highlighted through this work. The Quasi-Normal Modes (QNMs) of lossy plasmonic nanocavities were investigated across a wide range of geometric parameters including the nanoparticle diameter, gap refractive index, gap thickness, facet size and shape. We show that the gap thickness *t* and …

Optical nano-antennas: Fabrication, characterization and applications
… understanding of their spatial and spectral modes is gathered using finite-difference time domain simulations. The extremely high fields generated in gaps of closely coupled bowties are used in non-linear signal generation and several sum-frequency phenomena are identified. The sub-wavelength …

Selective excitation of adsorbate vibrations on dissipative surfaces
… also the coupling of the adsorbate ("system") modes to the electronic and phononic degrees of freedom of the surface ("bath") does. Vibrational relaxation thereby takes place, depending on the availabilty of energetically fitting electron-hole (e/h) pairs and/or phonons (lattice vibrations) in …
