QUANTUM MECHANICAL TREATMENT OF THE ELECTRICAL INTERACTION VIEWED AS AN ELASTIC COUPLING THROUGH FLUX LINES

Using the Lagrangian formalism we attempt to calculate the interaction energy between the two bodies, nonconnected and connected, in a linear lattice. The obtained results show that the interaction is dependent on the dispersion relation ω (q). On this basis we calculate the binding energy of an ionic lattice and we have found a good agreement with experimental data.
