%  For gold, typical values of the high-frequency permittivity $\epsilon_{\infty}$, the plasma frequency $\omega_{p}$, and the relaxation rate $\gamma$,  are: $\epsilon_{\infty}=9.5$, $\hbar\omega=8.95$ eV and $\hbar\gamma=69.1$  meV~\cite{Grady_2004}. Non-local A non-local  correction to the Drude model can also be included by considering the plasmon dispersion~\cite{Dobson_2000,Raza_2011}.  The metal (complex) permittivity then reads  %

Simple jellium geometries have been implemented in Octopus and they  can be used as effective ``superatomic pseudopotentials''. The similarity  between the  jellium potential and atomic pseudopotentials can be further exploited to develop an external ``jellium pseudopotential'' generator  to be used with Octopus. In this way, a larger selection of jellium  geometries will be made available along with refined, yet scalable,
