软凝聚态物理的理论研究

The achievement in research works:1..We studied a new puzzle currently rised in international journals about the slope of the temperature dependance of order arameter near transition emperature for nematic liquid crystal and proved that it is actually not exist.2.We developed a lattice Boltzmann method that ancorrectively describe the flow dynamics of nematic liquid crystal and did the simulation. The effect of flow dynamics on the phase of nematic liquid crystal is obtained. We clearly described its complicated phase separation and distribution.3..Theoretical studies on a method to detect the viscoce parameter of micell by means of light or neutron scattering. Our theory shows that the theoretical calculation can well fits with the experimental results, thus it supports the method of light and neutron scattering to detect the viscoce parameter.4.Our theoretical calculation well agrees with the phase seperation of ferrofluid at applied field in experiments.5..heoretical explanation of the statistical istribution of generation of the magnetic ball rings found in experiment in 2 dimensional space is carried out. The simulation is also done for 3 dimentional case. International conferences: Three time to be the member of nternationalorganizing committee of 9th, 10th and 11th nternational conference of discrete simulation of fluid dynamics and soft condensed matter. Organized the 11th international conference as a chairman.

软凝聚态物理是近十余年来迅速发展起来的一个重要领域,他是有结构的流体,又称复杂流体.它像固体凝聚态物质一样,有很丰富的,独特的功能,在材料,信息,交通,能源等领域有重要挠τ?本项目主要研究申请者已有一定研究工作积累的液晶相变理论, 晶格波尔茨曼理论方法及其对复杂流体的应用.基于我们的能计入短程位置关联的液晶广义分子场理论,对液晶相变和热力学性质作深入的研究;发展晶格波尔茨曼方法对复杂流体的应用..
