    • Pt = 14.0 GPa in a four-atom cell. All the electronic structure calculations were carried out with the projector augmented wave (PAW) method as implemented in the VASP code. The PW91 GGA exchange-correlation functional was used in the VC-NEB and G-SSNEB calculations at the transition pressure, with a plane-wave cutoffs of 450 eV and a 6×6×4Γ-centered Monkhorst-Pack k-point grids. 57 images and the climbing image NEB were implemented in both the VC-NEB and G-SSNEB calculations with no rotation-avoiding technique. The phase transition barrier for the VC-NEB calculation is 0.265 eV/formula and the G-SSNEB method gives the same barrier. The corresponding enthalpy of h-MgO metastable structure from the VC-NEB method is 0.12 eV/formula, which is close to 0.13 eV/formula reported in Ref. [28].
