Heat capacity anomaly near transitions between nematic and smectic phases and fluctuational nature of the NAC point
Anisimov M. A., Voronov V. P., Kul'kov A. O., Kholmurodov F.
The heat capacity has been studied near transitions between the nematic and smectic,4 and С phases of liquid-crystal mixture. The point at which the nematic-smectic C, nematic-smectic A, and smectic yi-smectic С lines intersect is also a tricritical point. A fluctuational increment in the heat capacity has been discovered on the line of A-C transitions.
