摘要: We have analysed theoretically the polarization and dielectric constant of uniaxial ionic crystals, including the effect of the nonlinear interactions between ions. The spectrum of polaritons (coupling modes of photons and optical phonons) under nonlinear interactions was developed. A new branch of dispersion relations emerges in the original frequency gap.
