abstract = {We report a molecular dynamics study on the effect of
electronic polarization on the structure and single-particle
dynamics of mixtures of the aprotic ionic liquid
1-ethyl-3-methylimidazolium
bis-(trifluoromethylsulfonyl)-imide ([EMIM][TFSI]) doped
with a lithium salt with the same anion at 298 K and 1 bar.
In particular, we analyze the effect of electron density
fluctuations on radial distribution functions, velocity
autocorrelation functions, cage correlation functions,
mean-squared displacements, and vibrational densities of
states, comparing the predictions of the
quantum-chemistry-based Atomistic Polarizable Potential for
Liquids, Electrolytes, $\&$ Polymers $(APPLE\&P)$ with those
of its nonpolarizable version and those of the standard
non-polarizable Optimized Potentials for Liquid
Simulations-All Atom (OPLS-AA). We found that the structure
of the mixture is scarcely modified by the fluctuations in
electron charge of their constituents, but their transport
properties are indeed quite drastically changed, with larger
mobilities being predicted for the different species in the
bulk mixtures with the polarizable force field.
Specifically, the mean-squared displacements are larger for
the polarizable potentials at identical time intervals and
the intermediate subdiffusive plateaus are greatly reduced,
so the transition to the diffusive regime takes place much
earlier than in the non-polarizable media. Moreover, the
correlations of the added cations inside their cages are
weakened out earlier and their vibrational densities of
states are slightly red-shifted, reflecting the weakening
effect of the electronic polarization on the Coulomb
coupling in these dense ionic media. The comparison of
OPLS-AA with non-polarizable $APPLE\&P$ indicates that
adding polarization to OPLS-AA is not sufficient to achieve
results close to experiments.},
