Modeling and theoretical description of magnetic hybrid materials - bridging from meso- to macro-scales

研究了磁性杂化材料在外加磁场和机械作用下的静态和动态响应。为此，明确的介观理论方法和统计多体理论得到了发展和应用。我们的理论描述磁性胶体颗粒之间的磁性和弹性相互作用嵌入弹性矩阵是由数值计算和模拟补充。作为一个中心方面，我们希望了解磁性胶体颗粒之间的集体相互作用如何影响宏观材料性质。通过这种方式，介观粒子水平与宏观长度尺度相连。

We investigate the static and dynamic response of magnetic hybrid materials to external magnetic and mechanical fields. For this purpose, explicit mesoscopic theoretical approaches and statistical many-body theories are developed and applied. Our theoretical descriptions of the magnetic and elastic interactions between the magnetic colloidal particles embedded in an elastic matrix are supplemented by numerical calculations and simulations. As a central aspect, we wish to understand how collective interactions between the magnetic colloidal particles influence the macroscopic material properties. In this way, the mesoscopic particle level is connected to the macroscopic length scales.
