Fig. 6: Self-energy and Eliashberg function of Li-doped graphene.

a Band map of Li-doped graphene along cut #2 from ref. 54 with two optimized linear bands, as well as the left-hand (L, blue) and right-hand (R, red) MDC maxima with 95% confidence intervals. b Comparison of α2FL(ω) (red) against α2FR(ω) (blue), with optimized model function mR(ω) (dash-dotted gold), based on the right-hand real \({\widetilde{\Sigma}}_{{\rm{R}}}^{{{{\prime} }}}(E)\) (green bars) and minus imaginary data \(-{\widetilde{\Sigma}}_{{\rm{R}}}^{\prime\prime}(E)\) (indigo bars), with reconstructions \({\Sigma }_{{\rm{R}}}^{{\prime} }(E)\) (green) and \(-{\Sigma }_{{\rm{R}}}^{{\prime} }(E)\) (indigo).
