Abstract
In this study, the free energies and specific heats of the nematic liquid crystals are studied within Tsallis thermostatistics. In equilibrium, free energy of PAA (para-azoxyanisole) vs the order parameter is plotted, as well as its the specific heat vs temperature. The effect of the nonextensivity is illustrated for some values of the entropic index q.
Highlights
The characteristic property of the mesophase of a nematic liquid crystal is its long-range orientational order
Maier-Saupe theory (MST) has been firstly generalized within Tsallis thermostatistics (TT) in [3] recently
We aims to investigate the free energy vs the order parameter and specific heat vs temperature by using generalized MST
Summary
The characteristic property of the mesophase of a nematic liquid crystal is its long-range orientational order. The definition of this orientational order is given by The orientational order decreases with the temperature and vanishes suddenly at the nematic-isotropic phase transition temperature at which a first-order phase transition occurs.
