Effect of smectic fluctuations on pretransitional phenomena in the isotropic phase of a nematic liquid crystal
Anisimov M. A., Gorodetskii E. F., Podnek V. E.
A new model that gives a unified description of the formation of nematic and smectic phases of liquid crystals is proposed. Including in this model the influence of smectic fluctuations on the transition from the isotropic liquid to the nematic phase has permitted explaining for the first time the anomalies in the thermodynamic quantities in the isotropic phase of liquid crystals with a narrow nematic region.
