Research themes of our group.

Theoretical Condensed Matter and Statistical Physics Group covers a large area of solid state physics and statistical physics, based on the two fundamental frameworks; quantum mechanics and statistical mechanics. Exotic, new and fundamental properties are of interest in highly correlated systems, soft materials, nano-materials, quasi-crystal and so on. Recently, research targets of the condensed mater theory are expanded to quantum information, topology, biomaterial, interdisciplinary region to the elementary particle physics, and general relativity. In addition to analytical approach, we perform numerical calculations for non-equilibrium systems or for electronic systems using sophisticated techniques. Domestic and international collaborations with experimental groups or industries stimulate our activities significantly. Every member of this group is available for discussions on a daily basis, thereby helping students to understand the many aspects of current physics.

The following lists the research subjects for each group member. Further details can be found from the Web, or direct contact with group members can be made by e-mail.
