Controlling the dynamics of active colloidal liquid crystals by external fields

在过去几年艾美诺特方案的资助下，该研究项目非常成功。关于活性胶体颗粒和活性胶体颗粒悬浮体的研究，包括活性胶体液晶，它们的动力学如何受到外场的影响，以及如何利用这些电场来控制它们的动力学，已经产生了几篇文章和软件，以及一项专利申请。一些出版物出现在影响很大的期刊上，并引起了媒体的大量报道。我们的一些成果开辟了重要的新研究方向，未来应该由单独的项目进一步研究。这些新的方向包括具有取向相关动机的胶体粒子的研究。本文提出了一个额外的子项目，为期6年，旨在追求在原项目的先前研究中出现的新的研究方向之一。在资助的第六年，应研究具有取向相关运动性的活性胶体液晶。这一新的子项目旨在研究具有取向相关运动的活性胶体液晶和不同类型活性胶体液晶混合物的集体动力学，外场对其集体动力学的影响，以及如何利用这些场来控制动力学。这项研究将运用理论物理的分析方法以及计算机模拟来进行。

In its past years of funding within the Emmy Noether programme, the research project was very successful. The research on active colloidal particles and suspensions of active colloidal particles including active colloidal liquid crystals, how their dynamics is affected by external fields, and how such fields can be used to control their dynamics, has already resulted in several publications, comprising articles and software, as well as a patent application. Some publications appeared in high-impact journals and resulted in large press coverage. A few of our results open up important new directions of research that should be further pursued by separate projects in the future. These new directions include the investigation of colloidal particles with orientation-dependent motility.This writing proposes an additional subproject for a 6th year of funding that aims at pursuing one of the new directions of research that arose during the previous research on the original project. In the 6th year of funding, active colloidal liquid crystals with orientation-dependent motility shall be investigated. The new subproject aims at studying the collective dynamics of active colloidal liquid crystals and mixtures of different types of active colloidal liquid crystals with an orientation-dependent motility, the effect of external fields on their collective dynamics, and how such fields can be used to control the dynamics. The research will be performed by applying analytical methods of theoretical physics as well as computer simulations.
