具有半柔性的边缘紧分形树
Marginally compact fractal trees with semiflexibility
摘要：
我们研究轻微紧凑的大分子树，通过两个不同的分形生成器创建。在这样做时，我们假设连接树的节点的向量的高斯统计。此外，我们引入债券债券的相关性，使树木局部半柔性。结构的对称性允许迭代构建完整的本征模集（尽管由于半柔性约束而存在额外的相互作用），使我们能够获得有关树行为的物理见解并考虑更大的结构。由于局部刚度，自接触密度急剧降低。
英文摘要：
We study marginally compact macromolecular trees that are created by means of two different fractal generators. In doing so, we assume Gaussian statistics for the vectors connecting nodes of the trees. Moreover, we introduce bond-bond correlations that make the trees locally semiflexible. The symmetry of the structures allows an iterative construction of full sets of eigenmodes (notwithstanding the additional interactions that are present due to semiflexibility constraints), enabling us to get physical insights about the trees' behavior and to consider larger structures. Due to the local stiffness the self-contact density gets drastically reduced.
