    • In Ref. [65] (i) they used modified forms for the phonon part of the SCDFT kernels, though the details of the modification have not yet been published (see Ref. [56] in Ref. [65]), (ii) they did not include the plasmon-induced dynamical effect, and (iii) their calculation was based on the local-density approximation, [67,68] which yielded a (Equation presented) structural transition point that is slightly different from that with the generalized-gradient approximation [35]
