| Outline of Final Research Achievements |
This work studies ordered states such as crystals, magnetic materials, and superfluids. In non-equilibrium, the ordered state are characterized by their topological structures, and the systems can have topological defects, the properties of which are determined by their topologies. The main purpose of this work is to quests universal statistical law in various dynamics of topological defects in various systems. The most successful result of this work is obtaining a new statistical law of quantum turbulence comprised of quantum vortices which are 1-dimensional topological defects in superfluids, when there are not only dynamical but also topological interactions between vortices.
