Research themes

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.
