Multi-plasmon effects and plasmon satellites in photoemission from nanostructures
P. A. D. Gonçalves, F. Javier García de Abajo
Plasmons can be excited during photoemission and produce spectral photoelectron features that yield information on the nanoscale optical response of the probed materials. However,…
Extremely confined gap plasmon modes: when nonlocality matters
Sergejs Boroviks, Zhan-Hong Lin, Vladimir A. Zenin +7
Historically, the field of plasmonics has been relying on the framework of classical electrodynamics, with the local-response approximation of material response being applied even…
Polaritons in two-dimensional parabolic waveguides
T. P. Rasmussen, P. A. D. Gonçalves, Sanshui Xiao +3
The suite of highly confined polaritons supported by two-dimensional (2D) materials constitutes a versatile platform for nano-optics, offering the means to channel light on deep-su…
Surface-response functions obtained from equilibrium electron-density profiles
N. Asger Mortensen, P. A. D. Gonçalves, Fedor A. Shuklin +4
Surface-response functions are one of the most promising routes for bridging the gap between fully quantum-mechanical calculations and phenomenological models in quantum nanoplasmo…
Probing Graphene's Nonlocality with Singular Metasurfaces
E. Galiffi, P. A. Huidobro, P. A. D. Gonçalves +2
Singular graphene metasurfaces, conductivity gratings realized by periodically suppressing the local doping level of a graphene sheet, have recently been proposed to efficiently ha…
On the applicability of quantum-optical concepts in strong-coupling nanophotonics
C. Tserkezis, A. I. Fernández-Domínguez, P. A. D. Gonçalves +7
Rooted in quantum optics and benefiting from its well-established foundations, strong coupling in nanophotonics has experienced increasing popularity in recent years. With nanophot…
