Calculation the bulk modulus obtained by fitting to the Murnaghan equation. The energy is plotted relative to the minimum energy for each case, -220.07 eV/atom in Fireball and -221.418 eV/atom for Quantum espresso using the pseudopotentials Te.pbe-mt_fhi.UPF . a0 and B0 are the equilibrium lattice constant and bulk modulus obtained by fitting to the Murnaghan equation of state.
