\label{fig:snapshot_copper} (color online). Snapshot Snapshots  of density change of $\mathrm{H^+}$ moving in $\mathrm{Cu}$ atoms with $v = 1.8 ~\mathrm{a.u.}$ (kinetic energy of $81 ~\mathrm{keV}$). The brown balls represents the $\mathrm{Cu}$ atoms and the single gray ball with light-blue-contours represents the incoming $\mathrm{H^+}$. $\mathrm{H^+}$ interacts with the $\mathrm{Cu}$ atoms charge density where some electron density is acquired during its trajectory. %  %\label{fig:snapshot_copper} (color online).
