Quantized polariton in ferroelectric Rochelle salt

ABSTRACT

In the presence of electric and gauge fields, it is possible to have effective charges, where an electron attached to an electric field flux can be termed a composite charge. Using the similar configuration of hydrogen, we calculate quantized energy eigenvalues for lattice ions, where the effective charge of an electron can assume a value of 0e or −2e and may be regarded as a photon composite; furthermore, polaritons from these composites can be quantized. We also compare our energy levels with experimental data obtained from inelastic neutron scatterings, in which the data above ∼ 3 meV ( = 24.1966 cm⁻¹) may be attributed to phonon modes in ferroelectric Rochelle salt.
