Calculation the bulk modulus obtained by fitting to the Murnaghan equation. The energy is plotted relative to the minimum energy for each case, -862.05 eV/atom in Fireball and -1159.43 eV/atom for Quantum espresso using the pseudopotentials Au.pbesol-dn-rrkjus_psl.0.1.UPF . a0 and B0 are the equilibrium lattice constant and bulk modulus obtained by fitting to the Murnaghan equation of state.

The cut off radio of the orbitals in Fireball are rs = 5.5 (bohr), rp = 5.5 (bohr), rd = 5.5 (bohr), and was generate like qs = 1.5, qp = 0.0, qd = 6.25, . The orbital p had been generated from the ion with charge qs = 0.0, qp = 0.0, qd = 0.0.
