Functional : LDA Ceperley/Alder Perdew/Zunger (1980)

Projection : Mulliken dipole

Calculation the bulk modulus obtained by fitting to the Murnaghan equation. The energy is plotted relative to the minimum energy for each case, -404.6 eV/atom in Fireball and -2847.13 eV/atom for Quantum espresso using the pseudopotentials Mn.pbe-sp-van.UPF . a0 and B0 are the equilibrium lattice constant and bulk modulus obtained by fitting to the Murnaghan equation of state.
