Dispersion relations of hybrid waves in dielectric media

详细

The dispersion relations of hybrid waves—polaritons, scalar bosons (hiddennons) and pseudoscalar bosons (axinons)—in one-dimensional dielectric media are derived with allowance for the resonant interaction between mechanical excitations of crystal lattices and elementary excitations of vacuum. It is shown that in the range of small wave vectors hybrid quasi-particles are formed in dielectric media: polaritons, hiddennons and axinons. For sodium nitrite crystal, dispersion relations of such hybrid quasiparticles are calculated near the center of the Brillouin zone. The resulting dispersion relations of hybrid quasi-particles provide conditions that allow observation of conversion of vacuum photon-like particles into hybrid quasi-particles in dielectrics, and also of parametric light scattering accompanied by the generation of hybrid quasi-particles.
