There is no simple L-J type expression for metallic bonding (some … NettetFourier transform of force constants at q are calculated from finite differences of forces induced on all the atoms of the supercell by the monochromatic perturbation. Advantages: • straightforward to implement Disadvantages: • limited to small supercells, i.e. q = G/n, where G is a reciprocal lattice vector
