title: Theoretical model of the frequency and temperature dependence of the complex non-linear dielectric effect in the isotropic phase above the isotropic-smectic-A phase transition.
abstract: Using the Landau model, the temperature and frequency dependence of the complex non-linear dielectric effect in the isotropic phase above the isotropic-smectic-A phase transition is calculated. Comparing the results of the calculations with existing data, we finally conclude that the model provides a description of the isotropic-smectic-A transition that takes all experimentally known features of the non-linear dielectric effect in the isotropic phase into account in a qualitatively correct way.
