Abstract

The influence of the dimerization process on the nematic ordering is investigated by using a nonextensive thermostatistics, namely Tsallis thermostatistics (TT). A theoretical model taking into account the dimerization influence on the nematic scalar order parameter has been recently presented (Phys. Lett. A 256 (1999) 309). Our study considers this model and the theoretical predictions for the nematic order parameter are improved by using TT. © 2003 Elsevier B.V. All rights reserved.
