(a) Simulation results of the dependence of Eex (red) and ECT (black) on dielectric constant. (b) The mean dependence of the ΔE = ECT − Eex on the reciprocal of dielectric constant. Error bars indicate uncertainty associated with finite sample size. Inset in (b) shows the equilibrium probability for a configuration to have a given value of ΔE at a specific dielectric constant.
