\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 presence of $\mathrm{H^+}$.  (a) Initial condition (b) representative steady condition after $91.64~\mathrm{attosecond}$  (see Fig. \ref{fig:energy_distance}).

Snapshot of density change of $\mathrm{H^+}$ moving in $\mathrm{Cu}$ atoms with $v = 1.8 ~\mathrm{a.u.}$ (kinetic energy of $81 ~\mathrm{keV}$) at $t = 91.65~\text{attoseconds}$. 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.
