AI中文摘要:
我们研究基于Landau-de Gennes模型的液晶各向同性-向列相界面问题。证明当各向异性弹性常数$L_2$为负时,各向同性-向列相界面的表面张力强度与$\boldsymbol{\boldsymbol{L}_1+\frac{2}{3}{L}_2}$的平方根成正比,且界面附近更倾向于垂直锚定取向。该结果严格证实了de Gennes在1971年提出的形式推导,即$L_2<0$时各向同性-向列相张力强度与锚定取向条件。
英文摘要:
We consider the isotropic-nematic interface problem for liquid crystals based on the Landau-de Gennes model. We show that when the anisotropic elastic constant $L_2$ is negative, then the surface tension strength of the isotropic-nematic interface is proportional to $\sqrt{L_1+\frac{2}{3}{L}_2}$, and the homeotropic alignment is more favored near the interface. This result gives a rigorous confirmation for de Gennes' formal derivation in \cite{deGen1971} on the isotropic-nematic tension strength and the anchoring alignment condition in the case of $L_2<0$.
