    • b, corresponding to the electrostatic energy of a plane capacitor. As we are only interested in energy differences, this contribution has been neglected.

    • For BLs, there exists no analogue for the correlation expression which was obtained with quantum simulations [14] for SLs. An approximate calculation of interlayer correlations in the liquid phase was worked out within the Singwi-Tosi-Land-Sjölander approach in ref. [17] and in ZHENG L. and MACDONALD A. H., Phys. Rev. B, 49 (1994) 5522.

    • note
    • The integrals in the first term in (3) and in the potential energy terms (third term in (3) and (4)) were conveniently performed in reciprocal space by Fourier-transforming ρ(r), while the remaining integrals were performed in real space. Typically, six shells both in direct and reciprocal lattices were used in the calculations.
