In this context, we proposed new model for solids representing as dielectric substance which is different from the well-known models of Einstein [2] and Debye [3] because: 1), we suggest that the atoms are the Fermi particles which are absent in the Einstein and Debye models; 2), we consider the stimulated oscillation of atoms by action of longitudinal and transverse lattice waves which in turn consist of the Sound Particles.
Thus, the elastic lattice waves stimulate the vibration of the fermion-atoms with one natural wavelength, we suggested that ions have two independent natural frequencies by under action of a longitudinal and a transverse wave.
Roy's concluding chapter on Ewald lattice simulation covers computer simulation of ionic folds, the convergence of lattice waves with atomic position, and vector potential convergence and atomic position.
