摘要 在这篇简短的评论中，我们总结了已经发表的结果，以证明高阶弹性项在向列液晶（NLC）胶体结构形成中的非常重要的作用。我们揭示了向列中的每个胶体粒子都可以有效地表示为非零弹性矩的三元组。通常，NLC 中的胶体颗粒仅用其弹性偶极矩和/或四极矩进行处理。但我们证明八极矩、十六极矩甚至 64 极矩也发挥着重要作用，并确定 NLC 中不同 1D、2D 甚至 3D 胶体晶体的参数。一般来说，前三个非零弹性矩的三元组可以描述迄今为止观察到的几乎所有胶体结构。偶极粒子应被视为具有偶极矩、四极矩和八极矩三元组的硬球体。四极粒子应被视为具有四极、十六极和 64 极弹性矩三元组的硬球 PACS 编号：61.30.Dk、82.70.Dd、64.70.M− 图解摘要
ABSTRACT In this short review we summarise already published results to manifest very important role of high order elastic terms in the formation of colloidal structures in nematic liquid crystals (NLC). We reveal that every colloidal particle in nematics can be effectively represented as a triad of nonzero elastic moments. Usually colloidal particles in NLCs are treated with their elastic dipole and/or quadrupole moments only. But we demonstrate that octupole, hexadecapole and even 64-pole moments play an important role as well and determine parameters of different 1D, 2D and even 3D colloidal crystals in NLCs. In general the triad of the first three nonzero elastic moments can describe almost all colloidal structures observed so far. Dipole particles should be considered as hard spheroids with a triad of the dipole, quadrupole and octupole moments. Quadrupole particles should be treated as hard spheres with a triad of quadrupole, hexadecapole and 64-pole elastic moments PACS numbers: 61.30.Dk, 82.70.Dd, 64.70.M− GRAPHICAL ABSTRACT
