    • The theoretical values of the pressures are calculated without the ZPE. The contribution from the ZPE is shown in the sections below with the comparison of the EOS's with the experimental ones.

    • As a check, we tried the calculation using the ABINIT code and the local pseudo-potential. The results with increased number of the q-points mesh for the Fourier transform, which is used to calculate the force constants from the dynamical matrix, show improvements of the long-wave phonon instability. See, X. Gonze, Phys. Rev. B 55, 10355 (1997) for the details of the calculation.
