The condensed matter theory group covers a large area of solid state physics and statistical physics, based on 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. 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 large group is available for discussions on a daily basis, thereby helping student to understand many aspects of current physics.
The following lists the research subjects for each groupmember. Further details can be found from the Web, or direct contact with group members can be made by e-mail.
