Anomolous electric conduction in transition metal oxides is currently the center of attentin in codensed matter physics. We are studying manganites and cuprates to elucidate mechanisms of colossal magnetoresistance and high-Tc superconductivity,respectively.

We are intersted in the dynamical response of clusters and molecules for their possible device applications. We also concern the self-organization of those materials, and manipulation by STM or AFM.

As a new quantum mechanical phenomenon, quantum geometric phase has been drawn much attention. We are doing research on the generation and control of electric current (or charge transfer) using the geometric phase idea. The geometric phase is also important in non-adiabatic phenomena that often occur in chemical reactions. We are also interested in such processes.
