The characteristic of nematic phase is orientation order of the molecule long axis 向列相的特征是分子長(zhǎng)軸取向有序,可用標(biāo)量序參量s表示。
In this paper , we introduce quantum theory into the liquid crystals in order to research the collective effect ( i . e . the physics effect produced by many - body effect and collective excitation ) . in this way , we research the microscopic theory of nematic phase and cholesteric phase 為了探索其集體效應(yīng)(多體效應(yīng)以及集體激發(fā)導(dǎo)致的物理效應(yīng)) ,本文將量子理論引入到液晶體系,研究向列相和膽甾相的微觀理論。
