| dc.description.abstract | Using mean field potential containing the lowest symmetry allowed first rank, second rank and coupling of the two terms, we have studied the ferroelectricity in nematic liquid crystals. By taking various combinations of the terms, we have designed a number of potential models and performed mean field calculations for each potential. The significance of a pure dipolar and coupling interaction terms are investigated . The pure dipolar interaction term has been found to show more influence than the coupling terms for the formation of ferroelectricity in nematic liquid crystal. Phase diagrams that show ferroelectric-nematic (FN ), nematic (N) and isotropic phases are produced for the various potential models | en_US |
