\label{fig:snapshot_copper} (color online). Snapshots of density change produced by a $\mathrm{H^+}$ moving in $\mathrm{Cu}$ atoms with $v = 1.8 ~\mathrm{a.u.}$ (kinetic energy of $81 ~\mathrm{keV}$) along the $\langle 100\rangle$ channeling trajectory. The brown balls represents the $\mathrm{Cu}$ atoms and the single gray ball with light-blue iso-density contours represents host electron density affected by  the incoming presence of  $\mathrm{H^+}$.$\mathrm{H^+}$ interacts with the host $\mathrm{Cu}$ electronic density.  (a) Initial condition (b) representative steady condition (see Fig. \ref{fig:energy_distance}).  Visualization produced with \textsc{VisIt}~\cite{Childs_2012}  %
