Panel (a): Absorption cross section of a pair of sodium nanowires. The external driving  electric field oscillates along is polarised as shown in  the $y$ direction (see inset). inset.  Curves are for different values of gap, $d$, between the nanowires, From top to bottom: $d=5,2,1,0.5,0.2,0.1,0$ nm. Panel (b): Field enhancement, $h$, for the case $d=0.5$ nm. The black lines indicate the nanowire surfaces.  (Adapted from Ref.~\cite{Stella_2013})\label{fig:plasmonics}
