    • As we have already mentioned in the Introduction, a model similar to the one in Eq. has been introduced earlier in the literature (Ref.) to study graphite intercalated compounds. The results presented in Ref. have no overlap with those presented in this paper since the authors of Ref.: (a) consider a superlattice, i.e., an infinite stack of graphene layers; (b) do not carry out extensive calculations of Fermi-liquid parameters; (c) do not study the dependence of interaction effects on the degree of density polarization; and (d) do not study the impact of exchange and correlation effects on the density partitioning.

    • 2 φ (ρ,z ) =0 for the electrical potential φ (ρ,z ) in cylindrical coordinates. The solution of the Poisson equation in all the N+1 regions can be written as φ(ρ,z) =exp (iqρ ) [αexp (qz ) + βexp (-qz )] and depends on a total of 2 (N+1 ) constants. Two are fixed by imposing boundary conditions φ (ρ,z→±) =0 at infinity. The remaining 2N constants are fixed by the continuity of the potential φ across each layer and by imposing that the electric displacement has a discontinuity. Let D= be the electric displacement above the th layer and Iμ be the dielectric constant in this region of space (E=-z φ ). Then one has to impose that D+1 - D=4π σfor =N,...,1, where σ=-e is the Fourier transform of -e δ2 (ρ) δ [z- (-1 ) d ]
