TL;DR: This theory explains surprisingly well both the frequency shifts and size-dependent damping in individual metallic nanoparticles as well as the observed broadening of the crossover regime from bonding-dipole plasmons to charge-transfer plasmon in metal nanoparticle dimers, thus unravelling a classical broadening mechanism that even dominates the widely anticipated short circuiting by quantum tunnelling.

TL;DR: The nonlocal hydrodynamic model and the recently introduced generalized nonlocal optical response (GNOR) model are thoroughly presented and the influence of nonlocal response on plasmonic excitations is studied in key metallic geometries.

TL;DR: This work presents a self-consistent hydrodynamic model (SC-HDM), where both the ground state and the excited state properties of an inhomogeneous electron gas can be determined, and is able to explain the size-dependent surface resonance shifts of Na and Ag nanowires and nanospheres.

TL;DR: In this article, the nonlocal response of a confined electron gas within the hydrodynamical Drude model was studied and it was shown that such resonances do indeed occur, but only above the plasma frequency.

TL;DR: This work numerically implements the hydrodynamical Drude model for arbitrary nanowire geometries, and finds that nonlocal response can strongly affect both the field enhancement in between the dimers and their respective extinction cross sections.
