Query: Single-atom control of the optoelectronic response in sub-nanometric
  cavities   By means of ab-initio time dependent density functional theory calculations
carried out on an prototypical hybrid plasmonic device (two metallic
nanoparticles bridged by a one-atom junction), we demonstrate the strong
interplay between photoinduced excitation of localized surface plasmons and
electron transport through the single atom. Such an interplay is remarkably
sensitive to the atomic orbitals of the junction. Therefore, we show the
possibility of a twofold tuning (plasmonic response and photoinduced current
across the juntion) just by changing a single atom in the device.
