Statistical Physics of Polymer and Related Systems

本课程将研究与材料科学相关的非平衡现象的介观描述。非平衡系统的模型将根据离散的时空映射来研究，这允许开发有效的计算工具。使用这种方法，动态标度特性将使用数值和分析技术进行研究，包括重整化群技术。在资助范围内研究的具体系统包括：聚合物系统的独立分解，包括流体动力学；晶体表面重组动力学；共存相序对旋量分解的影响聚合物晶体生长；凝胶化开始时的动态标度；和 , 硫化。

Research will be conducted on mesoscopic descriptions of non- equilibrium phenomena associated with materials science. Models of non-equilibrium systems will be studied in terms of discrete space- time maps, which permit efficient computational tools to be developed. Using this approach dynamical scaling properties will be studied using both numerical and analytical techniques, including renormalization group techniques. Specific systems to be studied within the scope of the grant include: spinodal decomposition of polymeric systems, including hydrodynamics; dynamics of crystal surface reorganization; the effect of coexisting phase ordering on spinodal decomposition; polymer crystal growth; dynamical scaling at the onset of gelation; and, vulcanization.
