ABSTRACT:

Quantum mechanism of interlayer polarization in condensed mediums in alternating electric field in the limits of low and extra-low temperatures is studied. Unbalanced density matrix is calculated for the ensemble of noninteracting protons, moving in one-dimension multipit potential image of rectangular shape in variable polarizing field. With the help of unbalanced density matrix, anomalous effects are studied, connected with the move of low-temperature maximum loss tangent of dielectric in lamellar crystals towards the temperatures of liquid helium. Results of quantum-mechanical calculation of spectra of complex dielectric permittivity (SCDP) may be used in the study of tunnel mechanism of spontaneous polarization of ferrielectrics (KDP, DKDP).

KEYWORDS: hydrogen – bonded crystals (HBC); interlayer polarization; proton relaxation; unbalanced proton density matrix; quantum statistic for the ensemble of non - interacting protons; spectra of complex dielectric permittivity (SCDP)
