| Outline of Final Research Achievements |
In order to clarify the crystal structures and novel physical properties of topological crystals, such as moebius-strip crystals, we have constructed theoretical frameworks to treat various mesoscopic phenomena, and also investigated physics in the systems where topology and geometry are important. Especially, we developed a new time-dependent Ginzeburg-Landau equations, in order to study the charge density wave dynamics in topological crystals, taking into account the interplay between microscopic quasi-particles and macroscopic condensate. We also studied the fluctuations and surface effects of the cuprate high-Tc superconductors at mesoscopic scales, based on phenomenological and microscopic treatment of the t-J model.
