| Abstract: | The physical properties of liquid crystals in an external field were investigated by means of solving the equation of a self-consistent field including an external field, Landau-Gennes free energy including an external fieId and Cotton-Mouton constant derived from microscopic theory were obtained. Meanwhile the critical phenomena induced by the external field were studied and the critical parameters were also obtained. |
