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 presence of $\mathrm{H^+}$.  From initial condition ($t=0$) to a representative steady condition after $t = 91.65~\mathrm{attosecond}$ (see Fig. \ref{fig:energy_distance}).  Visualization produced with \textsc{VisIt}~\cite{Childs_2012} \textsc{VisIt}~\cite{Childs_2012}.
