Next, we made an attempt to identify potential structural differences that may relate to the observed bimodal distribution of metallic and electrolyte states at 3.0 MPM. To this end, we examined 1000 configurations sampled every 20 fs from 4 AIMD trajectories at this concentration, to determine which snapshot corresponds to an electrolyte or a metal. Figure a,b demonstrates that the excess electron densities for subsequent electrolyte and metallic configurations overlap strongly. Nevertheless, for separately averaged electrolyte vs metallic configurations we see small but non-negligible alterations in the excess electron gyration radii and radial profiles, with the excess electron being slightly more spatially extended for the metal than the electrolyte (Figure ).
