A snapshots of the distribution of the charge density as a function of time for the simulation using VisIt~\cite{HPV:VisIt} are shown in Fig.~\ref{fig:snapshot_copper}. At $t = 0~\text{attoseconds}$ the $\mathrm{H^+}$ interacts with the neighboring $\mathrm{Cu}$ atoms charge density where some electron density is acquired. As $\mathrm{H^+}$ travels through the $\mathrm{Cu}$ crystal more electron density is acquired from the neighboring atoms as seen at $t = 91.65~\text{attoseconds}$.
