Research Subject Anomalous diffusion process is rather ubiquitous in complex systems. Examples include colloid diffusion in viscoelastic medium, motion of genetic loci inside cell nucleus, which can be observed by current single molecule observation techniques. In the present study, we focus on the effect of "negative" long range correlation. Such an effect is expected to show up in systems made of many connected elements, and generally leads to sub-diffusion dynamics in intermediate time scale. In addition to polymer, its generalization to D-dimensional manifold (polymerized membrane as a D=2 example), and the fluctuating interface as well belong to the realm of the connected system. From such a viewpoint, we aim to resolve how the anomalous dynamics emerges in mesoscopic scale of the hierarchical systems and explore its consequence on their functions.
